         * 99r25 Improvements in fixing discrepancies between covariates          * (Module): In version 0.99s4, we incorporated the calculation of
         missing in result line but in model.          the std error of the proportion of total life expectancy spent in
           a specific state Var(e.j/e..) using the formula of Var(X/Y)
 *Wed Mar 31 2021  Nicolas Brouard   <brouard@ined.fr>          depending only of the variances of X and Y and expectancies.
         * imach.c (Module): Still bugs in the result loop. Thank to Holly Benett

 *2021-03-08  Nicolas Brouard   <brouard@ined.fr>  
           * (Module): This version comes late after having tested
         * ./ (Module): Fixed bug on result:          successfully the praxis C version of Buckhardt.  But Buckardt's
           version was difficult to read and Gegenfurtner's version had a few
 *2021-02-20  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): Fix bug on quitting after result lines!          original PRAXIS program written in Algol W (published with errors,
         (Module): Version 0.99r21          ommitting the transposition of matrix V before its QR reduction
           from Golub. I used the recent "awe" compiler from Gkynn Webster.
 2021-02-12  Nicolas Brouard   <brouard@ined.fr>          The awe library had errors, for example in arc tangent function
           which have been fixed.
         * imach.c (Module): The use of a Windows BOM (huge) file is now an error  
           The main objective was to get identical results with the three
           versions: (1) Algol W, (2) Buckhardt'C version as well (3)
 2021-02-11  Nicolas  Brouard   <brouard@ined.fr>          Gegenfürtner C versions on the various test functions published by
           Brent in 1973 in Algol W.
         *  (Module): imach.c Someone entered 'results:' instead of 'result:'. Now it is an error which is printed.  
           Also, in order to compare them, the random function had to produce
 2020-02-22  Brouard Nicolas  <brouard@ined.fr>          the same sequence for the 3 softwares. The random function used in
           imach corresponds to original Brent's random function written in
         *  (Module): imach.c Update mle=-3 (for computing Life expectancy          Algol W.  Other point, in Algol W, the arrays of dimension n are
         and life table from the data without any state)          '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
 2019-05-20  Brouard Nicolas  <brouard@ined.fr>          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
         * version.h: Summary: version 0.99.r19          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: Summary: Projection syntax simplified          shifting the index from original X(I) in Algol W to x[i-1] in C.
         We can now start projections, forward or backward, from the mean date          But as IMaCh is using, since the beginning, the Numerical Recipes
         of inteviews up to or down to a number of years of projection:          functions vector or matrix, I changed Geggenfürtner code to mimick
         prevforecast=1 yearsfproj=15.3 mobil_average=0          the original Algol W arrays. Thus the X(I) is translated in C as
         or          x[i] which minimizes the errors. The Golub QR algorithm was
         prevforecast=1 starting-proj-date=1/1/2007 final-proj-date=12/31/2017 mobil_average=0          published in Algol with overflow errors which were reproduced in
         or          Brent's Algol W code. Buckhardt code fixed these errors which are
         prevbackcast=1 yearsbproj=12.3 mobil_average=1          much more problematic in C than in Algol W.  Thus Buckhardt code
         or          seems very safe, but i haven't chosen it for IMaCh because the C
         prevbackcast=1 starting-back-date=1/10/1999 final-back-date=1/1/1985 mobil_average=1          style is horrible and almost unreadable compared to Gegenfürtner
           CO code which is very close to Brent's original. Also what makes
 2019-05-18  Brouard Nicolas  <brouard@ined.fr>          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: doxygen tex bug          Brent's code or Gegenfürtner's code, the list of parameters is
           high. For example, the flin function LONG REAL PROCEDURE FLIN
 2019-05-16  Brouard Nicolas  <brouard@ined.fr>          (LONG REAL VALUE L) has only one parameter in Algol W, the
           Gegenfürtner flin function had two parameters: static double
         * imach.c: Summary: There was some wrong lines added          flin(l, j) double l; { int i; double tflin[N];} but Buckhardt
           function has 14 parameters which makes the code unreadable and
 2019-05-09  Brouard Nicolas  <brouard@ined.fr>          useless. Gegenfürtner used a lot of static variables or functions
           which I tried to minimize. Also in Gegefürtner, array dimensions
         * Makefile, imach.c: *** empty log message ***          were fixed to N. In my adaptation the flin is static double
           flin(double l, int j) and the parameter used are global variables.
         * ChangeLog: Summary: C=  
   2023-06-14  Nicolas Brouard   <brouard@ined.fr>
         * imach.c: Summary: Some updates

         * imach.c: Summary: 0.99r18 unlimited number of individuals          * imach.c (Module): Fixed PROB_r 
         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.

         * imach.c: Summary: Saito's color          * imach.c (Module): Version 0.99r33 A lot of changes in
           reassigning covariates: my first idea was that people will always
 2017-06-29  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: Summary: Version 0.99r14          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
 2017-06-27  Brouard Nicolas  <brouard@ined.fr>          three covariates (V1, V2, V3) the value of Tvaraff[j], but in fact
           the equation model is restricted to two variables only (V2, V3)
         * imach.c: Summary: More documentation on projections          and the combination for V2 should be codtabm(k,1) instead of
           (codtabm(k,2), and the code should be
         * imach.c: Summary: Color of backprojection changed from 6 to 5(yellow)          codtabm(k,TnsdVar[Tvaraff[j]]. Many many changes have been
           made. All of these should be simplified once a day like we did in
         * imach.c: Summary: Some bug with rint          hpxij() for example by using precov[nres] which is computed in
           decoderesult for each nres of each resultline. Loop should be done
