         * imach.c (Module): Fixed covariates (dummy or quantitative)          * imach.c (Module): s6 errors with age*age (harmless).
         with missing values have never been allowed but are ERRORS and  
         program quits. Standard deviations of fixed covariates were  2024-05-12  Nicolas Brouard   <brouard@ined.fr>
         wrongly computed. Mean and standard deviations of time varying  
         covariates are still not computed.          * imach.c Version 0.99s5 In fact, the covariance of total life
           expectancy e.. with a partial life expectancy e.j is high,
 2022-03-17  Brouard Nicolas  <brouard@ined.fr>          therefore the complete matrix of variance covariance has to be
           included in the formula of the standard error of the proportion of
         * 99r25 Improvements in fixing discrepancies between covariates          total life expectancy spent in a specific state:
         missing in result line but in model.          var(X/Y)=mu_x^2/mu_y^2*(sigma_x^2/mu_x^2 -2
           sigma_xy/mu_x/mu_y+sigma^2/mu_y^2).  Also an error with mle=-3
 *Wed Mar 31 2021  Nicolas Brouard   <brouard@ined.fr>          made the program core dump. It is fixed in this version.
         * imach.c (Module): Still bugs in the result loop. Thank to Holly Benett

           a specific state Var(e.j/e..) using the formula of Var(X/Y)
 *2021-02-20  Nicolas Brouard   <brouard@ined.fr>          depending only of the variances of X and Y and expectancies.
   
         * imach.c (Module): Fix bug on quitting after result lines!  2024-04-24  Nicolas Brouard   <brouard@ined.fr>
         (Module): Version 0.99r21  
           * (Module): This version comes late after having tested
 2021-02-12  Nicolas Brouard   <brouard@ined.fr>          successfully the praxis C version of Buckhardt.  But Buckardt's
           version was difficult to read and Gegenfurtner's version had a few
         * imach.c (Module): The use of a Windows BOM (huge) file is now an error          typos which made its results less reliable than Buckhardt's
           results.  The most important work consisted in retyping the Brent
           original PRAXIS program written in Algol W (published with errors,
 2021-02-11  Nicolas  Brouard   <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 Someone entered 'results:' instead of 'result:'. Now it is an error which is printed.          The awe library had errors, for example in arc tangent function
           which have been fixed.
 2020-02-22  Brouard Nicolas  <brouard@ined.fr>  
           The main objective was to get identical results with the three
         *  (Module): imach.c Update mle=-3 (for computing Life expectancy          versions: (1) Algol W, (2) Buckhardt'C version as well (3)
         and life table from the data without any state)          Gegenfürtner C versions on the various test functions published by
           Brent in 1973 in Algol W.
 2019-05-20  Brouard Nicolas  <brouard@ined.fr>  
           Also, in order to compare them, the random function had to produce
         * version.h: Summary: version 0.99.r19          the same sequence for the 3 softwares. The random function used in
           imach corresponds to original Brent's random function written in
         * imach.c: Summary: Projection syntax simplified          Algol W.  Other point, in Algol W, the arrays of dimension n are
         We can now start projections, forward or backward, from the mean date          'normal' mathematical arrays starting from 1 to n. But this is a
         of inteviews up to or down to a number of years of projection:          real issue in C where, by default, arrays are starting from 0 to
         prevforecast=1 yearsfproj=15.3 mobil_average=0          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
         prevforecast=1 starting-proj-date=1/1/2007 final-proj-date=12/31/2017 mobil_average=0          code are hesitating by changing either a loop originally from 1 to
         or          n in a loop from 0 to n-1, or keeping Brent's loop from 1 to n and
         prevbackcast=1 yearsbproj=12.3 mobil_average=1          shifting the index from original X(I) in Algol W to x[i-1] in C.
         or          But as IMaCh is using, since the beginning, the Numerical Recipes
         prevbackcast=1 starting-back-date=1/10/1999 final-back-date=1/1/1985 mobil_average=1          functions vector or matrix, I changed Geggenfürtner code to mimick
           the original Algol W arrays. Thus the X(I) is translated in C as
 2019-05-18  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: doxygen tex bug          Brent's Algol W code. Buckhardt code fixed these errors which are
           much more problematic in C than in Algol W.  Thus Buckhardt code
 2019-05-16  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
         * imach.c: Summary: There was some wrong lines added          CO code which is very close to Brent's original. Also what makes
           Buckhardt code more difficult to read is, instead of passing the
 2019-05-09  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
         * Makefile, imach.c: *** empty log message ***          high. For example, the flin function LONG REAL PROCEDURE FLIN
           (LONG REAL VALUE L) has only one parameter in Algol W, the
         * ChangeLog: Summary: C=          Gegenfürtner flin function had two parameters: static double
           flin(l, j) double l; { int i; double tflin[N];} but Buckhardt
         * imach.c: Summary: Some updates          function has 14 parameters which makes the code unreadable and
           useless. Gegenfürtner used a lot of static variables or functions
         * imach.c: Summary: Before ncovmax          which I tried to minimize. Also in Gegefürtner, array dimensions
           were fixed to N. In my adaptation the flin is static double
         * version.h: *** empty log message ***          flin(double l, int j) and the parameter used are global variables.
   
         * imach.c: Summary: 0.99r18 unlimited number of individuals  2023-06-14  Nicolas Brouard   <brouard@ined.fr>
         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 (Module): Testing if conjugate gradient could be quicker
