         * imach.c (Module): The use of a Windows BOM (huge) file is now an error  
           * (Module): This version comes late after having tested
           successfully the praxis C version of Buckhardt.  But Buckardt's
 2021-02-11  Nicolas  Brouard   <brouard@ined.fr>          version was difficult to read and Gegenfurtner's version had a few
           typos which made its results less reliable than Buckhardt's
         *  (Module): imach.c Someone entered 'results:' instead of 'result:'. Now it is an error which is printed.          results.  The most important work consisted in retyping the Brent
           original PRAXIS program written in Algol W (published with errors,
 2020-02-22  Brouard Nicolas  <brouard@ined.fr>          ommitting the transposition of matrix V before its QR reduction
           from Golub. I used the recent "awe" compiler from Gkynn Webster.
         *  (Module): imach.c Update mle=-3 (for computing Life expectancy          The awe library had errors, for example in arc tangent function
         and life table from the data without any state)          which have been fixed.
   
 2019-05-20  Brouard Nicolas  <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)
         * version.h: Summary: version 0.99.r19          Gegenfürtner C versions on the various test functions published by
           Brent in 1973 in Algol W.
         * imach.c: Summary: Projection syntax simplified  
         We can now start projections, forward or backward, from the mean date          Also, in order to compare them, the random function had to produce
         of inteviews up to or down to a number of years of projection:          the same sequence for the 3 softwares. The random function used in
         prevforecast=1 yearsfproj=15.3 mobil_average=0          imach corresponds to original Brent's random function written in
         or          Algol W.  Other point, in Algol W, the arrays of dimension n are
         prevforecast=1 starting-proj-date=1/1/2007 final-proj-date=12/31/2017 mobil_average=0          'normal' mathematical arrays starting from 1 to n. But this is a
         or          real issue in C where, by default, arrays are starting from 0 to
         prevbackcast=1 yearsbproj=12.3 mobil_average=1          n-1. In Buckhardt, as well as in Gegenfürtner C code, it can be
         or          seen that authors while trying to mimick original Brent Algol W
         prevbackcast=1 starting-back-date=1/10/1999 final-back-date=1/1/1985 mobil_average=1          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
 2019-05-18  Brouard Nicolas  <brouard@ined.fr>          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
         * imach.c: Summary: doxygen tex bug          functions vector or matrix, I changed Geggenfürtner code to mimick
           the original Algol W arrays. Thus the X(I) is translated in C as
 2019-05-16  Brouard Nicolas  <brouard@ined.fr>          x[i] which minimizes the errors. The Golub QR algorithm was
           published in Algol with overflow errors which were reproduced in
         * imach.c: Summary: There was some wrong lines added          Brent's Algol W code. Buckhardt code fixed these errors which are
           much more problematic in C than in Algol W.  Thus Buckhardt code
 2019-05-09  Brouard Nicolas  <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
         * Makefile, imach.c: *** empty log message ***          CO code which is very close to Brent's original. Also what makes
           Buckhardt code more difficult to read is, instead of passing the
         * ChangeLog: Summary: C=          minimum of parameters in the functions calls, as it is in Algol
           Brent's code or Gegenfürtner's code, the list of parameters is
         * imach.c: Summary: Some updates          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: Before ncovmax          Gegenfürtner flin function had two parameters: static double
           flin(l, j) double l; { int i; double tflin[N];} but Buckhardt
         * version.h: *** empty log message ***          function has 14 parameters which makes the code unreadable and
           useless. Gegenfürtner used a lot of static variables or functions
         * imach.c: Summary: 0.99r18 unlimited number of individuals          which I tried to minimize. Also in Gegefürtner, array dimensions
         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.          were fixed to N. In my adaptation the flin is static double
           flin(double l, int j) and the parameter used are global variables.

           deviation (needs data from the Hessian matrices) which slows the
