         *  (Module): imach.c Update mle=-3 (for computing Life expectancy          * imach.c (Module): Trying compiling on Linux with clang (instead
         and life table from the data without any state)          of gcc which is too slow) and lot of warnings suppressed

         * version.h: Summary: version 0.99.r19          * imach.c (Module): fixing some bugs in gnuplot and quantitative variables, but not completely solved
   
         * imach.c: Summary: Projection syntax simplified  2024-06-28  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:          * imach.c (Module): s6 errors with age*age (harmless).

         or  2024-05-12  Nicolas Brouard   <brouard@ined.fr>
         prevforecast=1 starting-proj-date=1/1/2007 final-proj-date=12/31/2017 mobil_average=0  
         or          * imach.c Version 0.99s5 In fact, the covariance of total life
         prevbackcast=1 yearsbproj=12.3 mobil_average=1          expectancy e.. with a partial life expectancy e.j is high,
         or          therefore the complete matrix of variance covariance has to be
         prevbackcast=1 starting-back-date=1/10/1999 final-back-date=1/1/1985 mobil_average=1          included in the formula of the standard error of the proportion of
           total life expectancy spent in a specific state:
 2019-05-18  Brouard Nicolas  <brouard@brouard.name>          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
         * imach.c: Summary: doxygen tex bug          made the program core dump. It is fixed in this version.
   
 2019-05-16  Brouard Nicolas  <brouard@brouard.name>  2024-04-30  Nicolas Brouard   <brouard@ined.fr>
   
         * imach.c: Summary: There was some wrong lines added          * (Module): In version 0.99s4, we incorporated the calculation of
           the std error of the proportion of total life expectancy spent in
 2019-05-09  Brouard Nicolas  <brouard@brouard.name>          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.

         * ChangeLog: Summary: C=  
           * (Module): This version comes late after having tested
         * imach.c: Summary: Some updates          successfully the praxis C version of Buckhardt.  But Buckardt's
           version was difficult to read and Gegenfurtner's version had a few
         * imach.c: Summary: Before ncovmax          typos which made its results less reliable than Buckhardt's
           results.  The most important work consisted in retyping the Brent
         * version.h: *** empty log message ***          original PRAXIS program written in Algol W (published with errors,
           ommitting the transposition of matrix V before its QR reduction
         * imach.c: Summary: 0.99r18 unlimited number of individuals          from Golub. I used the recent "awe" compiler from Gkynn Webster.
         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.          The awe library had errors, for example in arc tangent function
           which have been fixed.
 2018-12-13  Brouard Nicolas  <brouard@brouard.name>  
           The main objective was to get identical results with the three
         * imach.c: Summary: Bug for young ages (<-30) will be in r17          versions: (1) Algol W, (2) Buckhardt'C version as well (3)
           Gegenfürtner C versions on the various test functions published by
 2018-12-05  Brouard Nicolas  <brouard@brouard.name>          Brent in 1973 in Algol W.
   
         * Makefile: Summary: 0.99r16          Also, in order to compare them, the random function had to produce
           the same sequence for the 3 softwares. The random function used in
 2018-05-02  Brouard Nicolas  <brouard@brouard.name>          imach corresponds to original Brent's random function written in
           Algol W.  Other point, in Algol W, the arrays of dimension n are
         * imach.c: Summary: Some bugs fixed          '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
 2018-05-02  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          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
         * imach.c:  Summary: Bug for young ages (<-30) will be in r17          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
 2018-05-02  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          shifting the index from original X(I) in Algol W to x[i-1] in C.
           But as IMaCh is using, since the beginning, the Numerical Recipes
         * imach.c: Summary: Some bugs fixed          functions vector or matrix, I changed Geggenfürtner code to mimick
           the original Algol W arrays. Thus the X(I) is translated in C as
 2018-05-01  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:          Brent's Algol W code. Buckhardt code fixed these errors which are
         Summary: Bug fixed by providing frequencies only for non missing covariates          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
 2018-04-27  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          style is horrible and almost unreadable compared to Gegenfürtner
           CO code which is very close to Brent's original. Also what makes
         * imach.c: Summary: some minor bugs          Buckhardt code more difficult to read is, instead of passing the
           minimum of parameters in the functions calls, as it is in Algol
 2018-04-21  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          Brent's code or Gegenfürtner's code, the list of parameters is
           high. For example, the flin function LONG REAL PROCEDURE FLIN
         * README.txt: *** empty log message ***          (LONG REAL VALUE L) has only one parameter in Algol W, the
           Gegenfürtner flin function had two parameters: static double
         * imach.c: Summary: Some bugs fixed, valgrind tested          flin(l, j) double l; { int i; double tflin[N];} but Buckhardt
           function has 14 parameters which makes the code unreadable and
 2018-04-20  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          useless. Gegenfürtner used a lot of static variables or functions
           which I tried to minimize. Also in Gegefürtner, array dimensions
         * Makefile, README.txt, setup.iss: Summary: imach 0.99r16          were fixed to N. In my adaptation the flin is static double
           flin(double l, int j) and the parameter used are global variables.

           (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.
