         * imach.c (Module): Still bugs in the result loop. Thank to Holly Benett          * imach.c (Module): Trying compiling on Linux with clang (instead
           of gcc which is too slow) and lot of warnings suppressed
 2021-03-08  Nicolas Brouard   <brouard@ined.fr>  
   2024-06-28  Nicolas Brouard   <brouard@ined.fr>
         * ./ (Module): Fixed bug on result:  
           * imach.c (Module): fixing some bugs in gnuplot and quantitative variables, but not completely solved
 2021-02-20  Nicolas Brouard   <brouard@ined.fr>  
   2024-06-28  Nicolas Brouard  <brouard@ined.fr>
         * imach.c (Module): Fix bug on quitting after result lines!  
         (Module): Version 0.99r21          * imach.c (Module): s6 errors with age*age (harmless).
   
 2021-02-12  Nicolas Brouard   <brouard@ined.fr>  2024-05-12  Nicolas Brouard   <brouard@ined.fr>
   
         * imach.c (Module): The use of a Windows BOM (huge) file is now an error          * imach.c Version 0.99s5 In fact, the covariance of total life
           expectancy e.. with a partial life expectancy e.j is high,
           therefore the complete matrix of variance covariance has to be
 2021-02-11  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:
         *  (Module): imach.c Someone entered 'results:' instead of 'result:'. Now it is an error which is printed.          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
 2020-02-22  Brouard Nicolas  <brouard@ined.fr>          made the program core dump. It is fixed in this version.
   
         *  (Module): imach.c Update mle=-3 (for computing Life expectancy  2024-04-30  Nicolas Brouard   <brouard@ined.fr>
         and life table from the data without any state)  
           * (Module): In version 0.99s4, we incorporated the calculation of
 2019-05-20  Brouard Nicolas  <brouard@ined.fr>          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)
         * version.h: Summary: version 0.99.r19          depending only of the variances of X and Y and expectancies.
   
         * imach.c: Summary: Projection syntax simplified  2024-04-24  Nicolas Brouard   <brouard@ined.fr>
         We can now start projections, forward or backward, from the mean date  
         of inteviews up to or down to a number of years of projection:          * (Module): This version comes late after having tested
         prevforecast=1 yearsfproj=15.3 mobil_average=0          successfully the praxis C version of Buckhardt.  But Buckardt's
         or          version was difficult to read and Gegenfurtner's version had a few
         prevforecast=1 starting-proj-date=1/1/2007 final-proj-date=12/31/2017 mobil_average=0          typos which made its results less reliable than Buckhardt's
         or          results.  The most important work consisted in retyping the Brent
         prevbackcast=1 yearsbproj=12.3 mobil_average=1          original PRAXIS program written in Algol W (published with errors,
         or          ommitting the transposition of matrix V before its QR reduction
         prevbackcast=1 starting-back-date=1/10/1999 final-back-date=1/1/1985 mobil_average=1          from Golub. I used the recent "awe" compiler from Gkynn Webster.
           The awe library had errors, for example in arc tangent function
 2019-05-18  Brouard Nicolas  <brouard@ined.fr>          which have been fixed.
   
         * imach.c: Summary: doxygen tex bug          The main objective was to get identical results with the three
           versions: (1) Algol W, (2) Buckhardt'C version as well (3)
 2019-05-16  Brouard Nicolas  <brouard@ined.fr>          Gegenfürtner C versions on the various test functions published by
           Brent in 1973 in Algol W.
         * imach.c: Summary: There was some wrong lines added  
           Also, in order to compare them, the random function had to produce
 2019-05-09  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
         * Makefile, imach.c: *** empty log message ***          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
         * ChangeLog: Summary: C=          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
         * imach.c: Summary: Some updates          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: Before ncovmax          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.
         * version.h: *** empty log message ***          But as IMaCh is using, since the beginning, the Numerical Recipes
           functions vector or matrix, I changed Geggenfürtner code to mimick
         * imach.c: Summary: 0.99r18 unlimited number of individuals          the original Algol W arrays. Thus the X(I) is translated in C as
         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.          x[i] which minimizes the errors. The Golub QR algorithm was
           published in Algol with overflow errors which were reproduced in
 2018-12-13  Brouard Nicolas  <brouard@ined.fr>          Brent's Algol W code. Buckhardt code fixed these errors which are
           much more problematic in C than in Algol W.  Thus Buckhardt code
         * imach.c: Summary: Bug for young ages (<-30) will be in r17          seems very safe, but i haven't chosen it for IMaCh because the C
           style is horrible and almost unreadable compared to Gegenfürtner
 2018-12-05  Brouard Nicolas  <brouard@ined.fr>          CO code which is very close to Brent's original. Also what makes
           Buckhardt code more difficult to read is, instead of passing the
         * Makefile: Summary: 0.99r16          minimum of parameters in the functions calls, as it is in Algol
           Brent's code or Gegenfürtner's code, the list of parameters is
 2018-05-02  Brouard Nicolas  <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: Summary: Some bugs fixed          Gegenfürtner flin function had two parameters: static double
           flin(l, j) double l; { int i; double tflin[N];} but Buckhardt
 2018-05-02  Brouard Nicolas  <brouard@ined.fr>          function has 14 parameters which makes the code unreadable and
           useless. Gegenfürtner used a lot of static variables or functions
         * imach.c:  Summary: Bug for young ages (<-30) will be in r17          which I tried to minimize. Also in Gegefürtner, array dimensions
           were fixed to N. In my adaptation the flin is static double
 2018-05-02  Brouard Nicolas  <brouard@ined.fr>          flin(double l, int j) and the parameter used are global variables.
   
         * imach.c: Summary: Some bugs fixed  2023-06-14  Nicolas Brouard   <brouard@ined.fr>
   
 2018-05-01  Brouard Nicolas  <brouard@ined.fr>          * imach.c (Module): Testing if conjugate gradient could be quicker

         probabilities and covariance matrix          imach-114 because nhstepm was no more computed in the age
           loop. Now we define nhstepma in the age loop.
           (Module): In order to speed up (in case of numerous covariates) we
           compute health expectancies (without variances) in a first step
           and then all the health expectancies with variances or standard
           deviation (needs data from the Hessian matrices) which slows the
           computation.
           In the future we should be able to stop the program is only health
           expectancies and graph are needed without standard deviations.
