         * imach.c (Module): Fix bug on quitting after result lines!          * (Module): In version 0.99s4, we incorporated the calculation of

 2021-02-12  Nicolas Brouard   <brouard@ined.fr>          depending only of the variances of X and Y and expectancies.
   
         * imach.c (Module): The use of a Windows BOM (huge) file is now an error  2024-04-24  Nicolas Brouard   <brouard@ined.fr>
   
           * (Module): This version comes late after having tested
 2021-02-11  Nicolas  Brouard   <brouard@ined.fr>          successfully the praxis C version of Buckhardt.  But Buckardt's
           version was difficult to read and Gegenfurtner's version had a few
         *  (Module): imach.c Someone entered 'results:' instead of 'result:'. Now it is an error which is printed.          typos which made its results less reliable than Buckhardt's
           results.  The most important work consisted in retyping the Brent
 2020-02-22  Brouard Nicolas  <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 Update mle=-3 (for computing Life expectancy          from Golub. I used the recent "awe" compiler from Gkynn Webster.
         and life table from the data without any state)          The awe library had errors, for example in arc tangent function
           which have been fixed.
 2019-05-20  Brouard Nicolas  <brouard@ined.fr>  
           The main objective was to get identical results with the three
         * version.h: Summary: version 0.99.r19          versions: (1) Algol W, (2) Buckhardt'C version as well (3)
           Gegenfürtner C versions on the various test functions published by
         * imach.c: Summary: Projection syntax simplified          Brent in 1973 in Algol W.
         We can now start projections, forward or backward, from the mean date  
         of inteviews up to or down to a number of years of projection:          Also, in order to compare them, the random function had to produce
         prevforecast=1 yearsfproj=15.3 mobil_average=0          the same sequence for the 3 softwares. The random function used in
         or          imach corresponds to original Brent's random function written in
         prevforecast=1 starting-proj-date=1/1/2007 final-proj-date=12/31/2017 mobil_average=0          Algol W.  Other point, in Algol W, the arrays of dimension n are
         or          'normal' mathematical arrays starting from 1 to n. But this is a
         prevbackcast=1 yearsbproj=12.3 mobil_average=1          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
         prevbackcast=1 starting-back-date=1/10/1999 final-back-date=1/1/1985 mobil_average=1          seen that authors while trying to mimick original Brent Algol W
           code are hesitating by changing either a loop originally from 1 to
 2019-05-18  Brouard Nicolas  <brouard@ined.fr>          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: doxygen tex bug          But as IMaCh is using, since the beginning, the Numerical Recipes
           functions vector or matrix, I changed Geggenfürtner code to mimick
 2019-05-16  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: There was some wrong lines added          published in Algol with overflow errors which were reproduced in
           Brent's Algol W code. Buckhardt code fixed these errors which are
 2019-05-09  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
         * Makefile, imach.c: *** empty log message ***          style is horrible and almost unreadable compared to Gegenfürtner
           CO code which is very close to Brent's original. Also what makes
         * ChangeLog: Summary: C=          Buckhardt code more difficult to read is, instead of passing the
           minimum of parameters in the functions calls, as it is in Algol
         * imach.c: Summary: Some updates          Brent's code or Gegenfürtner's code, the list of parameters is
           high. For example, the flin function LONG REAL PROCEDURE FLIN
         * imach.c: Summary: Before ncovmax          (LONG REAL VALUE L) has only one parameter in Algol W, the
           Gegenfürtner flin function had two parameters: static double
         * version.h: *** empty log message ***          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: 0.99r18 unlimited number of individuals          useless. Gegenfürtner used a lot of static variables or functions
         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.          which I tried to minimize. Also in Gegefürtner, array dimensions
           were fixed to N. In my adaptation the flin is static double
 2018-12-13  Brouard Nicolas  <brouard@ined.fr>          flin(double l, int j) and the parameter used are global variables.

 2017-05-24  Brouard Nicolas  <brouard@ined.fr>          use the first covariate V1 into the model but in fact they are
           producing data with many covariates and can use an equation model
         * imach.c: *** empty log message ***          with some of the covariate; it means that in a model V2+V3 instead
           of codtabm(k,Tvaraff[j]) which calculates for combination k, for
 2017-05-23  Brouard Nicolas  <brouard@ined.fr>          three covariates (V1, V2, V3) the value of Tvaraff[j], but in fact
