         (Module): In order to speed up (in case of numerous covariates) we  2022-09-14  Nicolas Brouard   <brouard@ined.fr>
         compute health expectancies (without variances) in a first step  
         and then all the health expectancies with variances or standard          * imach.c (Module): Version 0.99r39 with colored dummy covariates

         computation.          ILK_parameter.txt file.
         In the future we should be able to stop the program is only health  
         expectancies and graph are needed without standard deviations.  2022-09-11  Nicolas Brouard   <brouard@ined.fr>
   
 2006-04-04  LIEVRE Agnes  <lievre@PC_00697.ined.fr>          * imach.c (Module): Adding timevarying products of any kinds,
           should work before shifting cotvar from ncovcol+nqv columns in

           the id of column.
         * imach.c (Module): bugs in evsi + population file added in htm output file          (Module): Some cleaning and adding covariates in ILK.txt

         name. <head> headers where missing.  
           * imach.c (Module): Now the easy runs i.e. without result or
         * Makefile (Module): 0.98g          model=1+age only did not work. The defautl combination should be 1
           and not 0 because everything hasn't been tranformed yet.
         * imach.c (Module): Weights can have a decimal point as for  
         English (a comma might work with a correct LC_NUMERIC environment,  2022-09-02  Nicolas Brouard   <brouard@ined.fr>
         otherwise the weight is truncated).  
         Modification of warning when the covariates values are not 0 or          * imach.c: Version 0.99r35 because it outputs same results with

         * Makefile (Module): Version 0.98f make _windows=1 imachcyg-setup          * imach.c (Module): Version 0.99r33 A lot of changes in
           reassigning covariates: my first idea was that people will always
         * imach.c (Module): refinements in the computation of lli if          use the first covariate V1 into the model but in fact they are
         status=-2 in order to have more reliable computation if stepm is          producing data with many covariates and can use an equation model
         not 1 month. Version 0.98f          with some of the covariate; it means that in a model V2+V3 instead
           of codtabm(k,Tvaraff[j]) which calculates for combination k, for
 2006-03-15  Brouard Nicolas  <brouard@localhost>          three covariates (V1, V2, V3) the value of Tvaraff[j], but in fact
           the equation model is restricted to two variables only (V2, V3)
         * imach.c (Module): Bug if status = -2, the loglikelihood was          and the combination for V2 should be codtabm(k,1) instead of
         computed as likelihood omitting the logarithm. Version O.98e          (codtabm(k,2), and the code should be
           codtabm(k,TnsdVar[Tvaraff[j]]. Many many changes have been
 2006-03-14  Brouard Nicolas  <brouard@localhost>          made. All of these should be simplified once a day like we did in
           hpxij() for example by using precov[nres] which is computed in
         * imach.c (Module): varevsij Comments added explaining the second          decoderesult for each nres of each resultline. Loop should be done
         table of variances if popbased=1 .          on the equation model globally by distinguishing only product with
         (Module): Covariances of eij, ekl added, graphs fixed, new html link.          age (which are changing with age) and no more on type of
         (Module): Function pstamp added          covariates, single dummies, single covariates.

           *  imach.c (Module): Version of imach using partly decoderesult to rebuild xpxij function
         * imach.c (Module): Variance-covariance wrong links and  
         varian-covariance of ej. is needed (Saito).  2022-08-03  Nicolas Brouard   <brouard@ined.fr>
   
 2006-02-27  Brouard Nicolas  <brouard@localhost>          *  imach.c (Module): Many errors in graphs fixed with Vn*age covariates.

 2006-02-24  Brouard Nicolas  <brouard@localhost>          * r29 W and not sqrt(Wald)
   
         * imach.c (Module): Memory leaks checks with valgrind and:  2022-07-22  Nicolas Brouard   <brouard@ined.fr>
         datafile was not closed, some imatrix were not freed and on matrix  
         allocation too.          *  imach.c (Module): Output of Wald test in the htm file and not only in the log. 
   
 2006-02-09  LIEVRE Agnes  <lievre@PC_00697.ined.fr>  2022-06-02  Brouard Nicolas  <brouard@brouard.name>
   
         * strsep.c (Module): Inclusion because not in mingw32!!!          * imach.c (Module): Adding the Wald tests from the log to the main

           * imach.c: With products of covariates (age or dummies or
         * Makefile (Module): IMACHSETUPVERSION added          quantitatives), estimates of parameters were good but when
           estimating variances the positions of newly created covariates
 2006-01-30  BROUARD Nicolas  <brouard@localhost>          were wrongly assigned and results were wrong. Thank to Feinua_Sun!

 2005-09-30    <lievre@PC_00595>  
           * imach.c (Module): Fixed covariates (dummy or quantitative)
         * imach.c (Module): sump fixed, loop imx fixed, and simplifications.          with missing values have never been allowed but are ERRORS and
         (Module): If the status is missing at the last wave but we know          program quits. Standard deviations of fixed covariates were
         that the person is alive, then we can code his/her status as -2          wrongly computed. Mean and standard deviations of time varying
         (instead of missing=-1 in earlier versions) and his/her          covariates are still not computed.
         contributions to the likelihood is 1 - Prob of dying from last

           * imach.c (Module): The use of a Windows BOM (huge) file is now an error
         * imach.c (Module): On windows (cygwin) function asctime_r doesn't  
         exist so I changed back to asctime which exists.

         (Repository): Because some people have very long ID (first column)  
         we changed int to long in num[] and we added a new lvector for          * Makefile, imach.c: *** empty log message ***

         health state: the date of the interview describes the actual state  
         and not the date of a change in health state. The former idea was  2018-04-27  Brouard Nicolas  <brouard@ined.fr>
         to consider that at each interview the state was recorded  
         (healthy, disable or death) and IMaCh was corrected; but when we          * imach.c: Summary: some minor bugs
         introduced the exact date of death then we should have modified  
         the contribution of an exact death to the likelihood. This new  2018-04-21  Brouard Nicolas  <brouard@ined.fr>
         contribution is smaller and very dependent of the step unit  
         stepm. It is no more the probability to die between last interview          * README.txt: *** empty log message ***
         and month of death but the probability to survive from last  
         interview up to one month before death multiplied by the          * imach.c: Summary: Some bugs fixed, valgrind tested

         Jackson for correcting this bug.  Former versions increased  2018-04-20  Brouard Nicolas  <brouard@ined.fr>
         mortality artificially. The bad side is that we add another loop  
           * Makefile, README.txt, setup.iss: Summary: imach 0.99r16

           to the period prevalence which wasn't computed accurately. The inner
           parameter ftolpl is now an outer parameter of the .imach parameter
           file after estepm. If ftolpl is small 1.e-4 and estepm too,
           computation are long.

           * imach.c (Module): Yes the sum of survivors was wrong since
           imach-114 because nhstepm was no more computed in the age
           loop. Now we define nhstepma in the age loop.
           (Module): In order to speed up (in case of numerous covariates) we
           compute health expectancies (without variances) in a first step
           and then all the health expectancies with variances or standard
           deviation (needs data from the Hessian matrices) which slows the
           computation.
           In the future we should be able to stop the program is only health
           expectancies and graph are needed without standard deviations.

           * imach.c (Module): sump fixed, loop imx fixed, and simplifications.
           (Module): If the status is missing at the last wave but we know
           that the person is alive, then we can code his/her status as -2
           (instead of missing=-1 in earlier versions) and his/her
           contributions to the likelihood is 1 - Prob of dying from last
           health status (= 1-p13= p11+p12 in the easiest case of somebody in
           the healthy state at last known wave). Version is 0.98 
   
   2004-05-20  Brouard Nicolas  <brouard@localhost>
   
           * imach.c (Repository): 
           Agnes added a direct estimation of mortality (without the need of
           computing period prevalence and differential mortality). Thus here
           is version 0.97a which has been distributed to some people at
           REVES 16 in Brugge using an Inno setup.exe for PCs. Estimates of
           mortality using covariates is not done today. Estimating direct
           mortality is a very different process because it doesn't need
           interpolation because it is easy to get the lx from the force of
           the mortality mux in the simplest case as for a Gompertz (log mux
           = a + b*x . But we have been able to incorporate the new code
           within former imach program (0.96d) without deteriorating too much
           the understanding of the program. 
   
   2003-06-25    <brouard@BROUARD>

           of the covariance matrix to be input.
   
   2003-06-25  Brouard Nicolas  <brouard@homebrou>
   
           * imach.c (Repository): Duplicated warning errors corrected.
           (Repository): Elapsed time after each iteration is now output. It
           helps to forecast when convergence will be reached. Elapsed time
           is stamped in powell.  We created a new html file for the graphs
           concerning matrix of covariance. It has extension -cov.htm.
   
   2003-06-23  Brouard Nicolas  <brouard@homebrou>
   
           * imach.c (Repository): Create a sub-directory where all the secondary files are. Only imach, htm, gp and r(imach) are on the main directory. Correct time and other things.

           * imach.c (Repository): Suppress abusive calls to append to file html (solution was to put fichtm as a global variable. Version 0.96

           * imach.c (Repository): Check when date of death was earlier that
           current date of interview. It may happen when the death was just
           prior to the death. In this case, dh was negative and likelihood
           was wrong (infinity). We still send an "Error" but patch by
           assuming that the date of death was just one stepm after the
           interview.
           (Repository): Because some people have very long ID (first column)
           we changed int to long in num[] and we added a new lvector for
           memory allocation. But we also truncated to 8 characters (left
           truncation)
   
           (Repository): No more line truncation errors.

           * imach.c (Repository): Add of a routine likelione (likelihood
           only once) which prints on a text file
           (ilk) the contributions to the likelihood for each
           individual/wave.
   
   2003-06-13  Brouard Nicolas  <brouard@homebrou>
           * imach.c (Repository): Replace "freqsummary" at a correct
           place. It differs from routine "prevalence" which may be called
           many times. Probs is memory consuming and must be used with
           parcimony.

           * timeval.h (Module): Added included file to make use of
           gettimeofday working on win32 with cygwin.
   
   2003-05-16  Brouard Nicolas  <brouard@brouard>
           * imach.c (Module): Insert of a warning if the delay between two
           waves is negative.
   
           * imach.c (Module):

           * imach.c: Some cleaning
   
   2003-03-28    <brouard@BROUARD>
           * imach.c (Module): In version up to 0.92 likelihood was computed
           as if date of death was unknown. Death was treated as any other
           health state: the date of the interview describes the actual state
           and not the date of a change in health state. The former idea was
           to consider that at each interview the state was recorded
           (healthy, disable or death) and IMaCh was corrected; but when we
           introduced the exact date of death then we should have modified
           the contribution of an exact death to the likelihood. This new
           contribution is smaller and very dependent of the step unit
           stepm. It is no more the probability to die between last interview
           and month of death but the probability to survive from last
           interview up to one month before death multiplied by the
           probability to die within a month. Thanks to Chris
           Jackson for correcting this bug.  Former versions increased
           mortality artificially. The bad side is that we add another loop
           which slows down the processing. The difference can be up to 10%
           lower mortality.

           * imach.c (Module): Add correlation matrix of one-step
           probabilities and covariance matrix
