         * imach.c (Module): Yes the sum of survivors was wrong since          *  imach.c (Module): Output of Wald test in the htm file and not only in the log. 
         imach-114 because nhstepm was no more computed in the age  
         loop. Now we define nhstepma in the age loop.  2022-05-30  Brouard Nicolas  <brouard@brouard.name>
         (Module): In order to speed up (in case of numerous covariates) we  
         compute health expectancies (without variances) in a first step          * imach.c: With products of covariates (age or dummies or
         and then all the health expectancies with variances or standard          quantitatives), estimates of parameters were good but when
         deviation (needs data from the Hessian matrices) which slows the          estimating variances the positions of newly created covariates
         computation.          were wrongly assigned and results were wrong. Thank to Feinua_Sun!
         In the future we should be able to stop the program is only health  
         expectancies and graph are needed without standard deviations.  2022-05-24  Nicolas Brouard   <brouard@ined.fr>

           * imach.c: Summary: Some bugs fixed
         * imach.c (Repository):  
         Agnes added a direct estimation of mortality (without the need of  2018-05-01  Brouard Nicolas  <brouard@ined.fr>
         computing period prevalence and differential mortality). Thus here  
         is version 0.97a which has been distributed to some people at          * imach.c:
         REVES 16 in Brugge using an Inno setup.exe for PCs. Estimates of          Summary: Bug fixed by providing frequencies only for non missing covariates
         mortality using covariates is not done today. Estimating direct  
         mortality is a very different process because it doesn't need  2018-04-27  Brouard Nicolas  <brouard@ined.fr>
         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          * imach.c: Summary: some minor bugs
         = a + b*x . But we have been able to incorporate the new code  
         within former imach program (0.96d) without deteriorating too much  2018-04-21  Brouard Nicolas  <brouard@ined.fr>
         the understanding of the program.

 2003-06-25    <brouard@BROUARD>  
           * imach.c: Summary: Some bugs fixed, valgrind tested
         * imach.c (Module): On windows (cygwin) function asctime_r doesn't  
         exist so I changed back to asctime which exists.  2018-04-20  Brouard Nicolas  <brouard@ined.fr>
         (Module): Version 0.96b  
           * Makefile, README.txt, setup.iss: Summary: imach 0.99r16
 2003-06-24    <brouard@BROUARD>  
           * imach.c:
         * imach.c (Module): Some bugs corrected for windows. Also, when          Summary: Computing mean and stdeviation of fixed quantitative variables
         mle=-1 a template is output in file "or"mypar.txt with the design  
         of the covariance matrix to be input.  2018-04-19  Brouard Nicolas  <brouard@ined.fr>

         (Repository): Elapsed time after each iteration is now output. It  
         helps to forecast when convergence will be reached. Elapsed time  2018-02-27  Brouard Nicolas  <brouard@ined.fr>
         is stamped in powell.  We created a new html file for the graphs

         * imach.c (Repository): Check when date of death was earlier that  2017-07-19  Brouard Nicolas  <brouard@ined.fr>
         current date of interview. It may happen when the death was just  
         prior to the death. In this case, dh was negative and likelihood          * imach.c: Summary: Bug for mobil_average=0 and prevforecast fixed(?)
         was wrong (infinity). We still send an "Error" but patch by  
         assuming that the date of death was just one stepm after the  2017-07-17  Brouard Nicolas  <brouard@ined.fr>
         interview.  
         (Repository): Because some people have very long ID (first column)          * imach.c: Summary: BOM files can be read now
         we changed int to long in num[] and we added a new lvector for  
         memory allocation. But we also truncated to 8 characters (left  2017-06-30  Brouard Nicolas  <brouard@ined.fr>
         truncation)

 2003-06-13  Brouard Nicolas  <brouard@homebrou>          * imach.c: Summary: More documentation on projections
         * imach.c (Repository): Replace "freqsummary" at a correct  
         place. It differs from routine "prevalence" which may be called          * imach.c: Summary: Color of backprojection changed from 6 to 5(yellow)
         many times. Probs is memory consuming and must be used with  
         parcimony.          * imach.c: Summary: Some bug with rint

         * 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          * imach.c: Summary: Version 0.99r13 (improvements and bugs fixed)
         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  2017-04-26  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: imach 0.99r13 Some bugs fixed
         introduced the exact date of death then we should have modified  
         the contribution of an exact death to the likelihood. This new          * imach.c: Summary: Labels in graphs
         contribution is smaller and very dependent of the step unit  
         stepm. It is no more the probability to die between last interview  2017-04-24  Brouard Nicolas  <brouard@ined.fr>
         and month of death but the probability to survive from last  
         interview up to one month before death multiplied by the          * imach.c: Summary: to save
         probability to die within a month. Thanks to Chris  
         Jackson for correcting this bug.  Former versions increased  2017-04-18  Brouard Nicolas  <brouard@ined.fr>
         mortality artificially. The bad side is that we add another loop  
           * imach.c: *** empty log message ***
   
         which slows down the processing. The difference can be up to 10%  2017-04-05  Brouard Nicolas  <brouard@ined.fr>

           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
           exist so I changed back to asctime which exists.
           (Module): Version 0.96b
   
   2003-06-24    <brouard@BROUARD>
   
           * imach.c (Module): Some bugs corrected for windows. Also, when
           mle=-1 a template is output in file "or"mypar.txt with the design
           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.
   
   2003-06-18  Brouard Nicolas  <brouard@homebrou>
   
           * imach.c (Repository): Suppress abusive calls to append to file html (solution was to put fichtm as a global variable. Version 0.96
   
   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.
   
   2003-06-14  Brouard Nicolas  <brouard@homebrou>
   
           * 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.
   
   2003-06-17    <brouard@BROUARD>
   
           * 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): 
   
   2003-05-03    <brouard@BROUARD>
   
           * 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.
   
   2002-05-30    <brouard@BROUARD>
           * 
           * imach.c (Module): Add correlation matrix of one-step
           probabilities and covariance matrix
