         * imach.c (Module): Some attempts to find a bug of wrong estimates          * (Module): This version comes late after having tested
         of confidencce intervals with product in the equation modelC          successfully the praxis C version of Buckhardt.  But Buckardt's
           version was difficult to read and Gegenfurtner's version had a few
 2022-05-15  Nicolas Brouard   <brouard@ined.fr>          typos which made its results less reliable than Buckhardt's
           results.  The most important work consisted in retyping the Brent
         * imach.c (Module):  Some minor improvements          original PRAXIS program written in Algol W (published with errors,
           ommitting the transposition of matrix V before its QR reduction
 2022-04-13  Brouard Nicolas  <brouard@brouard.name>          from Golub. I used the recent "awe" compiler from Gkynn Webster.
           The awe library had errors, for example in arc tangent function
         * imach.c (Module): Adding link to text data files          which have been fixed.
   
 2022-04-11  Nicolas Brouard   <brouard@ined.fr>          The main objective was to get identical results with the three
           versions: (1) Algol W, (2) Buckhardt'C version as well (3)
         * imach.c (Module): Error in rewriting the 'r' file with yearsfproj or yearsbproj fixed          Gegenfürtner C versions on the various test functions published by
           Brent in 1973 in Algol W.
 2022-04-05  Brouard Nicolas  <brouard@ined.fr>  
           Also, in order to compare them, the random function had to produce
         * imach.c (Module): Fixed covariates (dummy or quantitative)          the same sequence for the 3 softwares. The random function used in
         with missing values have never been allowed but are ERRORS and          imach corresponds to original Brent's random function written in
         program quits. Standard deviations of fixed covariates were          Algol W.  Other point, in Algol W, the arrays of dimension n are
         wrongly computed. Mean and standard deviations of time varying          'normal' mathematical arrays starting from 1 to n. But this is a
         covariates are still not computed.          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
 2022-03-17  Brouard Nicolas  <brouard@ined.fr>          seen that authors while trying to mimick original Brent Algol W
           code are hesitating by changing either a loop originally from 1 to
         * 99r25 Improvements in fixing discrepancies between covariates          n in a loop from 0 to n-1, or keeping Brent's loop from 1 to n and
         missing in result line but in model.          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
 *Wed Mar 31 2021  Nicolas Brouard   <brouard@ined.fr>          functions vector or matrix, I changed Geggenfürtner code to mimick
         * imach.c (Module): Still bugs in the result loop. Thank to Holly Benett          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
 *2021-03-08  Nicolas Brouard   <brouard@ined.fr>          published in Algol with overflow errors which were reproduced in
           Brent's Algol W code. Buckhardt code fixed these errors which are
         * ./ (Module): Fixed bug on result:          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
 *2021-02-20  Nicolas Brouard   <brouard@ined.fr>          style is horrible and almost unreadable compared to Gegenfürtner
           CO code which is very close to Brent's original. Also what makes
         * imach.c (Module): Fix bug on quitting after result lines!          Buckhardt code more difficult to read is, instead of passing the
         (Module): Version 0.99r21          minimum of parameters in the functions calls, as it is in Algol
           Brent's code or Gegenfürtner's code, the list of parameters is
 2021-02-12  Nicolas Brouard   <brouard@ined.fr>          high. For example, the flin function LONG REAL PROCEDURE FLIN
           (LONG REAL VALUE L) has only one parameter in Algol W, the
         * imach.c (Module): The use of a Windows BOM (huge) file is now an error          Gegenfürtner flin function had two parameters: static double
           flin(l, j) double l; { int i; double tflin[N];} but Buckhardt
           function has 14 parameters which makes the code unreadable and
 2021-02-11  Nicolas  Brouard   <brouard@ined.fr>          useless. Gegenfürtner used a lot of static variables or functions
           which I tried to minimize. Also in Gegefürtner, array dimensions
         *  (Module): imach.c Someone entered 'results:' instead of 'result:'. Now it is an error which is printed.          were fixed to N. In my adaptation the flin is static double
           flin(double l, int j) and the parameter used are global variables.
