         * imach.c: Summary: Some bugs fixed          * imach.c Version 0.99s5 In fact, the covariance of total life
           expectancy e.. with a partial life expectancy e.j is high,
 2018-05-01  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          therefore the complete matrix of variance covariance has to be
           included in the formula of the standard error of the proportion of

         Summary: Bug fixed by providing frequencies only for non missing covariates          var(X/Y)=mu_x^2/mu_y^2*(sigma_x^2/mu_x^2 -2
           sigma_xy/mu_x/mu_y+sigma^2/mu_y^2).  Also an error with mle=-3
 2018-04-27  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          made the program core dump. It is fixed in this version.
   
         * imach.c: Summary: some minor bugs  2024-04-30  Nicolas Brouard   <brouard@ined.fr>
   
 2018-04-21  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          * (Module): In version 0.99s4, we incorporated the calculation of
           the std error of the proportion of total life expectancy spent in
         * README.txt: *** empty log message ***          a specific state Var(e.j/e..) using the formula of Var(X/Y)
           depending only of the variances of X and Y and expectancies.
         * imach.c: Summary: Some bugs fixed, valgrind tested

           * (Module): This version comes late after having tested
         * Makefile, README.txt, setup.iss: Summary: imach 0.99r16          successfully the praxis C version of Buckhardt.  But Buckardt's
           version was difficult to read and Gegenfurtner's version had a few
         * imach.c:          typos which made its results less reliable than Buckhardt's
         Summary: Computing mean and stdeviation of fixed quantitative variables          results.  The most important work consisted in retyping the Brent
           original PRAXIS program written in Algol W (published with errors,
 2018-04-19  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          ommitting the transposition of matrix V before its QR reduction
           from Golub. I used the recent "awe" compiler from Gkynn Webster.
         * imach.c: Summary: Some minor bugs fixed          The awe library had errors, for example in arc tangent function
           which have been fixed.
         * version.h: *** empty log message ***  
           The main objective was to get identical results with the three
 2018-02-27  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          versions: (1) Algol W, (2) Buckhardt'C version as well (3)
           Gegenfürtner C versions on the various test functions published by
         * imach.c: *** empty log message ***          Brent in 1973 in Algol W.
   
         * imach.c: Summary: Adding second argument for quitting          Also, in order to compare them, the random function had to produce
           the same sequence for the 3 softwares. The random function used in
 2018-02-21  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          imach corresponds to original Brent's random function written in
           Algol W.  Other point, in Algol W, the arrays of dimension n are
         * Makefile, README.txt, imach.c: Summary: 0.99r15          'normal' mathematical arrays starting from 1 to n. But this is a
           real issue in C where, by default, arrays are starting from 0 to
         New Makefile with recent VirtualBox 5.26. Bug in sqrt negatve in imach.c          n-1. In Buckhardt, as well as in Gegenfürtner C code, it can be
           seen that authors while trying to mimick original Brent Algol W
 2017-07-20  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          code are hesitating by changing either a loop originally from 1 to
           n in a loop from 0 to n-1, or keeping Brent's loop from 1 to n and
         * imach.c: Summary: temporary working          shifting the index from original X(I) in Algol W to x[i-1] in C.
           But as IMaCh is using, since the beginning, the Numerical Recipes
 2017-07-19  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          functions vector or matrix, I changed Geggenfürtner code to mimick
           the original Algol W arrays. Thus the X(I) is translated in C as
         * imach.c: Summary: Bug for mobil_average=0 and prevforecast fixed(?)          x[i] which minimizes the errors. The Golub QR algorithm was
           published in Algol with overflow errors which were reproduced in
 2017-07-17  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          Brent's Algol W code. Buckhardt code fixed these errors which are
           much more problematic in C than in Algol W.  Thus Buckhardt code
         * imach.c: Summary: BOM files can be read now          seems very safe, but i haven't chosen it for IMaCh because the C
           style is horrible and almost unreadable compared to Gegenfürtner
 2017-06-30  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          CO code which is very close to Brent's original. Also what makes
           Buckhardt code more difficult to read is, instead of passing the
         * imach.c: Summary: Graphs improvements          minimum of parameters in the functions calls, as it is in Algol
           Brent's code or Gegenfürtner's code, the list of parameters is
         * imach.c: Summary: Saito's color          high. For example, the flin function LONG REAL PROCEDURE FLIN
           (LONG REAL VALUE L) has only one parameter in Algol W, the
 2017-06-29  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          Gegenfürtner flin function had two parameters: static double
           flin(l, j) double l; { int i; double tflin[N];} but Buckhardt
         * imach.c: Summary: Version 0.99r14          function has 14 parameters which makes the code unreadable and
           useless. Gegenfürtner used a lot of static variables or functions
 2017-06-27  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          which I tried to minimize. Also in Gegefürtner, array dimensions
           were fixed to N. In my adaptation the flin is static double
         * imach.c: Summary: More documentation on projections          flin(double l, int j) and the parameter used are global variables.
   
         * imach.c: Summary: Color of backprojection changed from 6 to 5(yellow)  2023-06-14  Nicolas Brouard   <brouard@ined.fr>

         * imach.c: *** empty log message ***          the equation model is restricted to two variables only (V2, V3)
           and the combination for V2 should be codtabm(k,1) instead of
 2016-09-02  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          (codtabm(k,2), and the code should be
           codtabm(k,TnsdVar[Tvaraff[j]]. Many many changes have been
         * imach.c: *** empty log message ***          made. All of these should be simplified once a day like we did in

           * 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.

           (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 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.

           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

           * imach.c: Some cleaning
   
   2003-03-28    <brouard@BROUARD>
