 2022-04-11  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): Error in rewriting the 'r' file with yearsfproj or yearsbproj fixed          version was difficult to read and Gegenfurtner's version had a few
           typos which made its results less reliable than Buckhardt's
 2022-04-05  Brouard Nicolas  <brouard@ined.fr>          results.  The most important work consisted in retyping the Brent
           original PRAXIS program written in Algol W (published with errors,

         wrongly computed. Mean and standard deviations of time varying          which have been fixed.
         covariates are still not computed.  
           The main objective was to get identical results with the three

         missing in result line but in model.  
           Also, in order to compare them, the random function had to produce

         * imach.c (Module): Still bugs in the result loop. Thank to Holly Benett          imach corresponds to original Brent's random function written in
           Algol W.  Other point, in Algol W, the arrays of dimension n are
 *2021-03-08  Nicolas Brouard   <brouard@ined.fr>          '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
         * ./ (Module): Fixed bug on result:          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
 *2021-02-20  Nicolas Brouard   <brouard@ined.fr>          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 (Module): Fix bug on quitting after result lines!          shifting the index from original X(I) in Algol W to x[i-1] in C.
         (Module): Version 0.99r21          But as IMaCh is using, since the beginning, the Numerical Recipes
           functions vector or matrix, I changed Geggenfürtner code to mimick
 2021-02-12  Nicolas Brouard   <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 (Module): The use of a Windows BOM (huge) file is now an error          published in Algol with overflow errors which were reproduced in
           Brent's Algol W code. Buckhardt code fixed these errors which are
           much more problematic in C than in Algol W.  Thus Buckhardt code
 2021-02-11  Nicolas  Brouard   <brouard@ined.fr>          seems very safe, but i haven't chosen it for IMaCh because the C
           style is horrible and almost unreadable compared to Gegenfürtner
         *  (Module): imach.c Someone entered 'results:' instead of 'result:'. Now it is an error which is printed.          CO code which is very close to Brent's original. Also what makes
           Buckhardt code more difficult to read is, instead of passing the
 2020-02-22  Brouard Nicolas  <brouard@ined.fr>          minimum of parameters in the functions calls, as it is in Algol
           Brent's code or Gegenfürtner's code, the list of parameters is
         *  (Module): imach.c Update mle=-3 (for computing Life expectancy          high. For example, the flin function LONG REAL PROCEDURE FLIN
         and life table from the data without any state)          (LONG REAL VALUE L) has only one parameter in Algol W, the
           Gegenfürtner flin function had two parameters: static double
 2019-05-20  Brouard Nicolas  <brouard@ined.fr>          flin(l, j) double l; { int i; double tflin[N];} but Buckhardt
           function has 14 parameters which makes the code unreadable and
         * version.h: Summary: version 0.99.r19          useless. Gegenfürtner used a lot of static variables or functions
           which I tried to minimize. Also in Gegefürtner, array dimensions
         * imach.c: Summary: Projection syntax simplified          were fixed to N. In my adaptation the flin is static double

         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.
