         *  (Module): imach.c Update mle=-3 (for computing Life expectancy          * (Module): In version 0.99s4, we incorporated the calculation of
         and life table from the data without any state)          the std error of the proportion of total life expectancy spent in
           a specific state Var(e.j/e..) using the formula of Var(X/Y)
 2019-05-20  Brouard Nicolas  <brouard@brouard.name>          depending only of the variances of X and Y and expectancies.
   
         * version.h: Summary: version 0.99.r19  2024-04-24  Nicolas Brouard   <brouard@ined.fr>
   
         * imach.c: Summary: Projection syntax simplified          * (Module): This version comes late after having tested
         We can now start projections, forward or backward, from the mean date          successfully the praxis C version of Buckhardt.  But Buckardt's
         of inteviews up to or down to a number of years of projection:          version was difficult to read and Gegenfurtner's version had a few
         prevforecast=1 yearsfproj=15.3 mobil_average=0          typos which made its results less reliable than Buckhardt's
         or          results.  The most important work consisted in retyping the Brent
         prevforecast=1 starting-proj-date=1/1/2007 final-proj-date=12/31/2017 mobil_average=0          original PRAXIS program written in Algol W (published with errors,
         or          ommitting the transposition of matrix V before its QR reduction
         prevbackcast=1 yearsbproj=12.3 mobil_average=1          from Golub. I used the recent "awe" compiler from Gkynn Webster.
         or          The awe library had errors, for example in arc tangent function
         prevbackcast=1 starting-back-date=1/10/1999 final-back-date=1/1/1985 mobil_average=1          which have been fixed.
   
 2019-05-18  Brouard Nicolas  <brouard@brouard.name>          The main objective was to get identical results with the three
           versions: (1) Algol W, (2) Buckhardt'C version as well (3)
         * imach.c: Summary: doxygen tex bug          Gegenfürtner C versions on the various test functions published by
           Brent in 1973 in Algol W.
 2019-05-16  Brouard Nicolas  <brouard@brouard.name>  
           Also, in order to compare them, the random function had to produce
         * imach.c: Summary: There was some wrong lines added          the same sequence for the 3 softwares. The random function used in
           imach corresponds to original Brent's random function written in
 2019-05-09  Brouard Nicolas  <brouard@brouard.name>          Algol W.  Other point, in Algol W, the arrays of dimension n are
           'normal' mathematical arrays starting from 1 to n. But this is a
         * Makefile, imach.c: *** empty log message ***          real issue in C where, by default, arrays are starting from 0 to
           n-1. In Buckhardt, as well as in Gegenfürtner C code, it can be
         * ChangeLog: Summary: C=          seen that authors while trying to mimick original Brent Algol W
           code are hesitating by changing either a loop originally from 1 to
         * imach.c: Summary: Some updates          n in a loop from 0 to n-1, or keeping Brent's loop from 1 to n and
           shifting the index from original X(I) in Algol W to x[i-1] in C.
         * imach.c: Summary: Before ncovmax          But as IMaCh is using, since the beginning, the Numerical Recipes
           functions vector or matrix, I changed Geggenfürtner code to mimick
         * version.h: *** empty log message ***          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: 0.99r18 unlimited number of individuals          published in Algol with overflow errors which were reproduced in
         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.          Brent's Algol W code. Buckhardt code fixed these errors which are
           much more problematic in C than in Algol W.  Thus Buckhardt code
 2018-12-13  Brouard Nicolas  <brouard@brouard.name>          seems very safe, but i haven't chosen it for IMaCh because the C
           style is horrible and almost unreadable compared to Gegenfürtner
         * imach.c: Summary: Bug for young ages (<-30) will be in r17          CO code which is very close to Brent's original. Also what makes
           Buckhardt code more difficult to read is, instead of passing the
 2018-12-05  Brouard Nicolas  <brouard@brouard.name>          minimum of parameters in the functions calls, as it is in Algol
           Brent's code or Gegenfürtner's code, the list of parameters is
         * Makefile: Summary: 0.99r16          high. For example, the flin function LONG REAL PROCEDURE FLIN
           (LONG REAL VALUE L) has only one parameter in Algol W, the
 2018-05-02  Brouard Nicolas  <brouard@brouard.name>          Gegenfürtner flin function had two parameters: static double
           flin(l, j) double l; { int i; double tflin[N];} but Buckhardt
         * imach.c: Summary: Some bugs fixed          function has 14 parameters which makes the code unreadable and
           useless. Gegenfürtner used a lot of static variables or functions
 2018-05-02  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: Bug for young ages (<-30) will be in r17          flin(double l, int j) and the parameter used are global variables.
