         * imach.c (Module): Adding link to text data files          * (Module): In version 0.99s4, we incorporated the calculation of

           * (Module): This version comes late after having tested
         * imach.c (Module): Fixed covariates (dummy or quantitative)          successfully the praxis C version of Buckhardt.  But Buckardt's
         with missing values have never been allowed but are ERRORS and          version was difficult to read and Gegenfurtner's version had a few
         program quits. Standard deviations of fixed covariates were          typos which made its results less reliable than Buckhardt's
         wrongly computed. Mean and standard deviations of time varying          results.  The most important work consisted in retyping the Brent
         covariates are still not computed.          original PRAXIS program written in Algol W (published with errors,

           The main objective was to get identical results with the three

         * imach.c (Module): Still bugs in the result loop. Thank to Holly Benett          Gegenfürtner C versions on the various test functions published by
           Brent in 1973 in Algol W.
 *2021-03-08  Nicolas Brouard   <brouard@ined.fr>  
           Also, in order to compare them, the random function had to produce
         * ./ (Module): Fixed bug on result:          the same sequence for the 3 softwares. The random function used in
           imach corresponds to original Brent's random function written in
 *2021-02-20  Nicolas Brouard   <brouard@ined.fr>          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
         * imach.c (Module): Fix bug on quitting after result lines!          real issue in C where, by default, arrays are starting from 0 to
         (Module): Version 0.99r21          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
 2021-02-12  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): The use of a Windows BOM (huge) file is now an error          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
           functions vector or matrix, I changed Geggenfürtner code to mimick
 2021-02-11  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
         *  (Module): imach.c Someone entered 'results:' instead of 'result:'. Now it is an error which is printed.          published in Algol with overflow errors which were reproduced in
           Brent's Algol W code. Buckhardt code fixed these errors which are
 2020-02-22  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
         *  (Module): imach.c Update mle=-3 (for computing Life expectancy          style is horrible and almost unreadable compared to Gegenfürtner
         and life table from the data without any state)          CO code which is very close to Brent's original. Also what makes
           Buckhardt code more difficult to read is, instead of passing the
 2019-05-20  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
         * version.h: Summary: version 0.99.r19          high. For example, the flin function LONG REAL PROCEDURE FLIN
           (LONG REAL VALUE L) has only one parameter in Algol W, the
         * imach.c: Summary: Projection syntax simplified          Gegenfürtner flin function had two parameters: static double
         We can now start projections, forward or backward, from the mean date          flin(l, j) double l; { int i; double tflin[N];} but Buckhardt
         of inteviews up to or down to a number of years of projection:          function has 14 parameters which makes the code unreadable and
         prevforecast=1 yearsfproj=15.3 mobil_average=0          useless. Gegenfürtner used a lot of static variables or functions
         or          which I tried to minimize. Also in Gegefürtner, array dimensions
         prevforecast=1 starting-proj-date=1/1/2007 final-proj-date=12/31/2017 mobil_average=0          were fixed to N. In my adaptation the flin is static double
         or          flin(double l, int j) and the parameter used are global variables.
