         * version.h: Summary: version 0.99.r19          * imach.c (Module): Trying compiling on Linux with clang (instead
           of gcc which is too slow) and lot of warnings suppressed
         * imach.c: Summary: Projection syntax simplified  
         We can now start projections, forward or backward, from the mean date  2024-06-28  Nicolas Brouard   <brouard@ined.fr>
         of inteviews up to or down to a number of years of projection:  
         prevforecast=1 yearsfproj=15.3 mobil_average=0          * imach.c (Module): fixing some bugs in gnuplot and quantitative variables, but not completely solved
         or

 2019-05-18  Brouard Nicolas  <brouard@brouard.name>          * imach.c Version 0.99s5 In fact, the covariance of total life
           expectancy e.. with a partial life expectancy e.j is high,
         * imach.c: Summary: doxygen tex bug          therefore the complete matrix of variance covariance has to be
           included in the formula of the standard error of the proportion of
 2019-05-16  Brouard Nicolas  <brouard@brouard.name>          total life expectancy spent in a specific state:
           var(X/Y)=mu_x^2/mu_y^2*(sigma_x^2/mu_x^2 -2
         * imach.c: Summary: There was some wrong lines added          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.

         * Makefile, imach.c: *** empty log message ***

         * imach.c: Summary: Before ncovmax  2024-04-24  Nicolas Brouard   <brouard@ined.fr>
   
         * version.h: *** empty log message ***          * (Module): This version comes late after having tested
           successfully the praxis C version of Buckhardt.  But Buckardt's
         * imach.c: Summary: 0.99r18 unlimited number of individuals          version was difficult to read and Gegenfurtner's version had a few
         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.          typos which made its results less reliable than Buckhardt's
           results.  The most important work consisted in retyping the Brent
 2018-12-13  Brouard Nicolas  <brouard@brouard.name>          original PRAXIS program written in Algol W (published with errors,
           ommitting the transposition of matrix V before its QR reduction
         * imach.c: Summary: Bug for young ages (<-30) will be in r17          from Golub. I used the recent "awe" compiler from Gkynn Webster.
           The awe library had errors, for example in arc tangent function
 2018-12-05  Brouard Nicolas  <brouard@brouard.name>          which have been fixed.
   
         * Makefile: Summary: 0.99r16          The main objective was to get identical results with the three
           versions: (1) Algol W, (2) Buckhardt'C version as well (3)
 2018-05-02  Brouard Nicolas  <brouard@brouard.name>          Gegenfürtner C versions on the various test functions published by
           Brent in 1973 in Algol W.
         * imach.c: Summary: Some bugs fixed  
           Also, in order to compare them, the random function had to produce
 2018-05-02  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          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: Bug for young ages (<-30) will be in r17          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
 2018-05-02  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          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 bugs fixed          seen that authors while trying to mimick original Brent Algol W
           code are hesitating by changing either a loop originally from 1 to
 2018-05-01  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          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.
         * imach.c:          But as IMaCh is using, since the beginning, the Numerical Recipes
         Summary: Bug fixed by providing frequencies only for non missing covariates          functions vector or matrix, I changed Geggenfürtner code to mimick
           the original Algol W arrays. Thus the X(I) is translated in C as
 2018-04-27  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          x[i] which minimizes the errors. The Golub QR algorithm was
           published in Algol with overflow errors which were reproduced in
         * imach.c: Summary: some minor bugs          Brent's Algol W code. Buckhardt code fixed these errors which are
           much more problematic in C than in Algol W.  Thus Buckhardt code
 2018-04-21  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          seems very safe, but i haven't chosen it for IMaCh because the C
           style is horrible and almost unreadable compared to Gegenfürtner
         * README.txt: *** 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
         * imach.c: Summary: Some bugs fixed, valgrind tested          minimum of parameters in the functions calls, as it is in Algol
           Brent's code or Gegenfürtner's code, the list of parameters is
 2018-04-20  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          high. For example, the flin function LONG REAL PROCEDURE FLIN
           (LONG REAL VALUE L) has only one parameter in Algol W, the
         * Makefile, README.txt, setup.iss: Summary: imach 0.99r16          Gegenfürtner flin function had two parameters: static double
           flin(l, j) double l; { int i; double tflin[N];} but Buckhardt
         * imach.c:          function has 14 parameters which makes the code unreadable and
         Summary: Computing mean and stdeviation of fixed quantitative variables          useless. Gegenfürtner used a lot of static variables or functions
           which I tried to minimize. Also in Gegefürtner, array dimensions
 2018-04-19  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          were fixed to N. In my adaptation the flin is static double
           flin(double l, int j) and the parameter used are global variables.
         * imach.c: Summary: Some minor bugs fixed  
   2023-06-14  Nicolas Brouard   <brouard@ined.fr>
         * version.h: *** empty log message ***

           (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.
