         (Module): Version 0.98nR Running ok, but output format still only works for three covariates.  
           * imach.c (Module): Version 0.99r42 needed a newer version of
 2010-04-29  brouard  <brouard@ined.fr>          Gnuplot. But newer version 0.99r43 should run with the Gnuplot

         * imach.c (Module): Yes the sum of survivors was wrong since  2022-09-11  Nicolas Brouard   <brouard@ined.fr>
         imach-114 because nhstepm was no more computed in the age  
         loop. Now we define nhstepma in the age loop.          * imach.c (Module): Adding timevarying products of any kinds,
         (Module): In order to speed up (in case of numerous covariates) we          should work before shifting cotvar from ncovcol+nqv columns in

   2022-09-02  Nicolas Brouard   <brouard@ined.fr>
 2006-03-20  Brouard Nicolas  <brouard@localhost>

         English (a comma might work with a correct LC_NUMERIC environment,  
         otherwise the weight is truncated).  2022-08-21  Nicolas Brouard   <brouard@ined.fr>
         Modification of warning when the covariates values are not 0 or  
         1.          * imach.c (Module): Version 0.99r33 A lot of changes in
         Version 0.98g          reassigning covariates: my first idea was that people will always
           use the first covariate V1 into the model but in fact they are
 2006-03-16  LIEVRE Agnes  <lievre@PC_00697.ined.fr>          producing data with many covariates and can use an equation model
           with some of the covariate; it means that in a model V2+V3 instead
         * imach.c (Module): Comments concerning covariates added          of codtabm(k,Tvaraff[j]) which calculates for combination k, for
           three covariates (V1, V2, V3) the value of Tvaraff[j], but in fact
         * noreg-setup.iss (Module): Version 0.98f          the equation model is restricted to two variables only (V2, V3)
           and the combination for V2 should be codtabm(k,1) instead of
         * Makefile (Module): Version 0.98f make _windows=1 imachcyg-setup          (codtabm(k,2), and the code should be
           codtabm(k,TnsdVar[Tvaraff[j]]. Many many changes have been
         * imach.c (Module): refinements in the computation of lli if          made. All of these should be simplified once a day like we did in
         status=-2 in order to have more reliable computation if stepm is          hpxij() for example by using precov[nres] which is computed in
         not 1 month. Version 0.98f          decoderesult for each nres of each resultline. Loop should be done
           on the equation model globally by distinguishing only product with
 2006-03-15  Brouard Nicolas  <brouard@localhost>          age (which are changing with age) and no more on type of
           covariates, single dummies, single covariates. 
         * imach.c (Module): Bug if status = -2, the loglikelihood was  
         computed as likelihood omitting the logarithm. Version O.98e  2022-08-06  Nicolas Brouard   <brouard@ined.fr>

 2006-03-06  Brouard Nicolas  <brouard@localhost>          * imach.c (Module): Error cptcovn instead of nsd in bmij (was
           coredumped, revealed by Feiuno, thank you.
         * imach.c (Module): Variance-covariance wrong links and  
         varian-covariance of ej. is needed (Saito).  2022-07-23  Nicolas Brouard   <brouard@ined.fr>
   
 2006-02-27  Brouard Nicolas  <brouard@localhost>          * r29 W and not sqrt(Wald)

 2006-02-24  Brouard Nicolas  <brouard@localhost>          htm for better display of the maximum likelihood estimators.
   
         * imach.c (Module): Memory leaks checks with valgrind and:  2022-05-30  Brouard Nicolas  <brouard@brouard.name>
         datafile was not closed, some imatrix were not freed and on matrix  
         allocation too.          * imach.c: With products of covariates (age or dummies or
           quantitatives), estimates of parameters were good but when
 2006-02-09  LIEVRE Agnes  <lievre@PC_00697.ined.fr>          estimating variances the positions of newly created covariates
           were wrongly assigned and results were wrong. Thank to Feinua_Sun!

         * imach.c (Module): Comments (lines starting with a #) are allowed in data.          * imach.c (Module): Fixed covariates (dummy or quantitative)
           with missing values have never been allowed but are ERRORS and
 2005-10-25  Nicolas Brouard  <brouard@dhcp171.recherche.ined.fr>          program quits. Standard deviations of fixed covariates were
           wrongly computed. Mean and standard deviations of time varying
         * Makefile (Module): Added Imach98.pmsp and howto crete a dmg          covariates are still not computed.

           missing in result line but in model. 
         * imach.c (Module): sump fixed, loop imx fixed, and simplifications.  
         (Module): If the status is missing at the last wave but we know  *Wed Mar 31 2021  Nicolas Brouard   <brouard@ined.fr>
         that the person is alive, then we can code his/her status as -2          * imach.c (Module): Still bugs in the result loop. Thank to Holly Benett

         REVES 16 in Brugge using an Inno setup.exe for PCs. Estimates of  
         mortality using covariates is not done today. Estimating direct          * imach.c (Module): The use of a Windows BOM (huge) file is now an error
         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  2021-02-11  Nicolas  Brouard   <brouard@ined.fr>

         (Repository): Because some people have very long ID (first column)          * version.h: *** empty log message ***
         we changed int to long in num[] and we added a new lvector for  
         memory allocation. But we also truncated to 8 characters (left          * imach.c: Summary: 0.99r18 unlimited number of individuals
         truncation)          The number n which was limited to 20,000 cases is now unlimited, from firstobs to lastobs. If the number is too for the virtual memory, probably an error will occur.

         to consider that at each interview the state was recorded  2018-04-20  Brouard Nicolas  <brouard@ined.fr>
         (healthy, disable or death) and IMaCh was corrected; but when we  
         introduced the exact date of death then we should have modified          * Makefile, README.txt, setup.iss: Summary: imach 0.99r16
         the contribution of an exact death to the likelihood. This new  
         contribution is smaller and very dependent of the step unit          * imach.c:

         probability to die within a month. Thanks to Chris  
         Jackson for correcting this bug.  Former versions increased          * imach.c: Summary: Some minor bugs fixed

           Author: N Brouard
   
           We had difficulties to get smoothed confidence intervals. It was due
           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.

   2006-04-28  Brouard Nicolas  <brouard@localhost>
   
           * 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>
   
           * imach.c (Module): On windows (cygwin) function asctime_r doesn't

   2003-06-24    <brouard@BROUARD>
   
           * imach.c (Module): Some bugs corrected for windows. Also, when

           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>

   2003-06-17  Brouard Nicolas  <brouard@homebrou>
   
   
           * 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.

           * 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.

           * imach.c (Module): Insert of a warning if the delay between two
           waves is negative.
   
           * imach.c (Module):

           * imach.c: Some cleaning

           * 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
