         * imach.c (Module): Error in rewriting the 'r' file with yearsfproj or yearsbproj fixed          * imach.c (Module): Some bug fixes: in drawings when age*age is
           included in the model as well as with quantitative variables.
 2022-04-05  Brouard Nicolas  <brouard@ined.fr>  
   2024-07-02  Nicolas Brouard  <brouard@ined.fr>
         * imach.c (Module): Fixed covariates (dummy or quantitative)  
         with missing values have never been allowed but are ERRORS and          * imach.c (Module): Trying compiling on Linux with clang (instead
         program quits. Standard deviations of fixed covariates were          of gcc which is too slow) and lot of warnings suppressed
         wrongly computed. Mean and standard deviations of time varying  
         covariates are still not computed.  2024-06-28  Nicolas Brouard   <brouard@ined.fr>
   
 2022-03-17  Brouard Nicolas  <brouard@ined.fr>          * imach.c (Module): fixing some bugs in gnuplot and quantitative
           variables, but not completely solved
         * 99r25 Improvements in fixing discrepancies between covariates  
         missing in result line but in model.  2024-06-28  Nicolas Brouard  <brouard@ined.fr>
   
 *Wed Mar 31 2021  Nicolas Brouard   <brouard@ined.fr>          * imach.c (Module): s6 errors with age*age (harmless).
         * imach.c (Module): Still bugs in the result loop. Thank to Holly Benett

 *2021-03-08  Nicolas Brouard   <brouard@ined.fr>  
           * imach.c Version 0.99s5 In fact, the covariance of total life
         * ./ (Module): Fixed bug on result:          expectancy e.. with a partial life expectancy e.j is high,
           therefore the complete matrix of variance covariance has to be
 *2021-02-20  Nicolas Brouard   <brouard@ined.fr>          included in the formula of the standard error of the proportion of
           total life expectancy spent in a specific state:
         * imach.c (Module): Fix bug on quitting after result lines!          var(X/Y)=mu_x^2/mu_y^2*(sigma_x^2/mu_x^2 -2
         (Module): Version 0.99r21          sigma_xy/mu_x/mu_y+sigma^2/mu_y^2).  Also an error with mle=-3
           made the program core dump. It is fixed in this version.
 2021-02-12  Nicolas Brouard   <brouard@ined.fr>  
   2024-04-30  Nicolas Brouard   <brouard@ined.fr>
         * imach.c (Module): The use of a Windows BOM (huge) file is now an error  
           * (Module): In version 0.99s4, we incorporated the calculation of
           the std error of the proportion of total life expectancy spent in
 2021-02-11  Nicolas  Brouard   <brouard@ined.fr>          a specific state Var(e.j/e..) using the formula of Var(X/Y)
           depending only of the variances of X and Y and expectancies.
         *  (Module): imach.c Someone entered 'results:' instead of 'result:'. Now it is an error which is printed.  
   2024-04-24  Nicolas Brouard   <brouard@ined.fr>
 2020-02-22  Brouard Nicolas  <brouard@ined.fr>  
           * (Module): This version comes late after having tested
         *  (Module): imach.c Update mle=-3 (for computing Life expectancy          successfully the praxis C version of Buckhardt.  But Buckardt's
         and life table from the data without any state)          version was difficult to read and Gegenfurtner's version had a few
           typos which made its results less reliable than Buckhardt's
 2019-05-20  Brouard Nicolas  <brouard@ined.fr>          results.  The most important work consisted in retyping the Brent
           original PRAXIS program written in Algol W (published with errors,
         * version.h: Summary: version 0.99.r19          ommitting the transposition of matrix V before its QR reduction
           from Golub. I used the recent "awe" compiler from Gkynn Webster.
         * imach.c: Summary: Projection syntax simplified          The awe library had errors, for example in arc tangent function
         We can now start projections, forward or backward, from the mean date          which have been fixed.
         of inteviews up to or down to a number of years of projection:  
         prevforecast=1 yearsfproj=15.3 mobil_average=0          The main objective was to get identical results with the three
         or          versions: (1) Algol W, (2) Buckhardt'C version as well (3)
         prevforecast=1 starting-proj-date=1/1/2007 final-proj-date=12/31/2017 mobil_average=0          Gegenfürtner C versions on the various test functions published by
         or          Brent in 1973 in Algol W.
         prevbackcast=1 yearsbproj=12.3 mobil_average=1  
         or          Also, in order to compare them, the random function had to produce
         prevbackcast=1 starting-back-date=1/10/1999 final-back-date=1/1/1985 mobil_average=1          the same sequence for the 3 softwares. The random function used in
           imach corresponds to original Brent's random function written in
 2019-05-18  Brouard Nicolas  <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: Summary: doxygen tex bug          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
 2019-05-16  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
         * imach.c: Summary: There was some wrong lines added          n in a loop from 0 to n-1, or keeping Brent's loop from 1 to n and
           shifting the index from original X(I) in Algol W to x[i-1] in C.
 2019-05-09  Brouard Nicolas  <brouard@ined.fr>          But as IMaCh is using, since the beginning, the Numerical Recipes
           functions vector or matrix, I changed Geggenfürtner code to mimick
         * Makefile, imach.c: *** empty log message ***          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
         * ChangeLog: Summary: C=          published in Algol with overflow errors which were reproduced in
           Brent's Algol W code. Buckhardt code fixed these errors which are
         * imach.c: Summary: Some updates          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
         * imach.c: Summary: Before ncovmax          style is horrible and almost unreadable compared to Gegenfürtner
           CO code which is very close to Brent's original. Also what makes
         * version.h: *** empty log message ***          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: 0.99r18 unlimited number of individuals          Brent's code or Gegenfürtner's code, the list of parameters is
         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.          high. For example, the flin function LONG REAL PROCEDURE FLIN
           (LONG REAL VALUE L) has only one parameter in Algol W, the
 2018-12-13  Brouard Nicolas  <brouard@ined.fr>          Gegenfürtner flin function had two parameters: static double
           flin(l, j) double l; { int i; double tflin[N];} but Buckhardt
         * imach.c: Summary: Bug for young ages (<-30) will be in r17          function has 14 parameters which makes the code unreadable and
           useless. Gegenfürtner used a lot of static variables or functions
 2018-12-05  Brouard Nicolas  <brouard@ined.fr>          which I tried to minimize. Also in Gegefürtner, array dimensions
           were fixed to N. In my adaptation the flin is static double
         * Makefile: Summary: 0.99r16          flin(double l, int j) and the parameter used are global variables.
