         * imach.c (Module): Adding link to text data files          * imach.c (Module): Trying compiling on Linux with clang (instead
           of gcc which is too slow) and lot of warnings suppressed

         program quits. Standard deviations of fixed covariates were  
         wrongly computed. Mean and standard deviations of time varying  2024-05-12  Nicolas Brouard   <brouard@ined.fr>
         covariates are still not computed.  
           * imach.c Version 0.99s5 In fact, the covariance of total life
 2022-03-17  Brouard Nicolas  <brouard@ined.fr>          expectancy e.. with a partial life expectancy e.j is high,
           therefore the complete matrix of variance covariance has to be
         * 99r25 Improvements in fixing discrepancies between covariates          included in the formula of the standard error of the proportion of
         missing in result line but in model.          total life expectancy spent in a specific state:

         * ./ (Module): Fixed bug on result:          * (Module): In version 0.99s4, we incorporated the calculation of
           the std error of the proportion of total life expectancy spent in
 *2021-02-20  Nicolas Brouard   <brouard@ined.fr>          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 (Module): Fix bug on quitting after result lines!  
         (Module): Version 0.99r21  2024-04-24  Nicolas Brouard   <brouard@ined.fr>
   
 2021-02-12  Nicolas Brouard   <brouard@ined.fr>          * (Module): This version comes late after having tested
           successfully the praxis C version of Buckhardt.  But Buckardt's
         * imach.c (Module): The use of a Windows BOM (huge) file is now an error          version was difficult to read and Gegenfurtner's version had a few
           typos which made its results less reliable than Buckhardt's
           results.  The most important work consisted in retyping the Brent
 2021-02-11  Nicolas  Brouard   <brouard@ined.fr>          original PRAXIS program written in Algol W (published with errors,
           ommitting the transposition of matrix V before its QR reduction
         *  (Module): imach.c Someone entered 'results:' instead of 'result:'. Now it is an error which is printed.          from Golub. I used the recent "awe" compiler from Gkynn Webster.
           The awe library had errors, for example in arc tangent function
 2020-02-22  Brouard Nicolas  <brouard@ined.fr>          which have been fixed.
   
         *  (Module): imach.c Update mle=-3 (for computing Life expectancy          The main objective was to get identical results with the three
         and life table from the data without any state)          versions: (1) Algol W, (2) Buckhardt'C version as well (3)
           Gegenfürtner C versions on the various test functions published by
 2019-05-20  Brouard Nicolas  <brouard@ined.fr>          Brent in 1973 in Algol W.
   
         * version.h: Summary: version 0.99.r19          Also, in order to compare them, the random function had to produce
           the same sequence for the 3 softwares. The random function used in
         * imach.c: Summary: Projection syntax simplified          imach corresponds to original Brent's random function written in
         We can now start projections, forward or backward, from the mean date          Algol W.  Other point, in Algol W, the arrays of dimension n are
         of inteviews up to or down to a number of years of projection:          'normal' mathematical arrays starting from 1 to n. But this is a
         prevforecast=1 yearsfproj=15.3 mobil_average=0          real issue in C where, by default, arrays are starting from 0 to
         or          n-1. In Buckhardt, as well as in Gegenfürtner C code, it can be
         prevforecast=1 starting-proj-date=1/1/2007 final-proj-date=12/31/2017 mobil_average=0          seen that authors while trying to mimick original Brent Algol W
         or          code are hesitating by changing either a loop originally from 1 to
         prevbackcast=1 yearsbproj=12.3 mobil_average=1          n in a loop from 0 to n-1, or keeping Brent's loop from 1 to n and
         or          shifting the index from original X(I) in Algol W to x[i-1] in C.
         prevbackcast=1 starting-back-date=1/10/1999 final-back-date=1/1/1985 mobil_average=1          But as IMaCh is using, since the beginning, the Numerical Recipes
           functions vector or matrix, I changed Geggenfürtner code to mimick
 2019-05-18  Brouard Nicolas  <brouard@ined.fr>          the original Algol W arrays. Thus the X(I) is translated in C as
           x[i] which minimizes the errors. The Golub QR algorithm was
         * imach.c: Summary: doxygen tex bug          published in Algol with overflow errors which were reproduced in
           Brent's Algol W code. Buckhardt code fixed these errors which are
 2019-05-16  Brouard Nicolas  <brouard@ined.fr>          much more problematic in C than in Algol W.  Thus Buckhardt code
           seems very safe, but i haven't chosen it for IMaCh because the C
         * imach.c: Summary: There was some wrong lines added          style is horrible and almost unreadable compared to Gegenfürtner
           CO code which is very close to Brent's original. Also what makes
 2019-05-09  Brouard Nicolas  <brouard@ined.fr>          Buckhardt code more difficult to read is, instead of passing the
           minimum of parameters in the functions calls, as it is in Algol
         * Makefile, imach.c: *** empty log message ***          Brent's code or Gegenfürtner's code, the list of parameters is
           high. For example, the flin function LONG REAL PROCEDURE FLIN
         * ChangeLog: Summary: C=          (LONG REAL VALUE L) has only one parameter in Algol W, the
           Gegenfürtner flin function had two parameters: static double
         * imach.c: Summary: Some updates          flin(l, j) double l; { int i; double tflin[N];} but Buckhardt
           function has 14 parameters which makes the code unreadable and
         * imach.c: Summary: Before ncovmax          useless. Gegenfürtner used a lot of static variables or functions
           which I tried to minimize. Also in Gegefürtner, array dimensions
         * version.h: *** empty log message ***          were fixed to N. In my adaptation the flin is static double
           flin(double l, int j) and the parameter used are global variables.
         * imach.c: Summary: 0.99r18 unlimited number of individuals  
         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.  2023-06-14  Nicolas Brouard   <brouard@ined.fr>
   
 2018-12-13  Brouard Nicolas  <brouard@ined.fr>          * imach.c (Module): Testing if conjugate gradient could be quicker
