         * imach.c (Module): Fix bug on quitting after result lines!          * imach.c Version 0.99s5 In fact, the covariance of total life
           expectancy e.. with a partial life expectancy e.j is high,
 2021-02-12  Nicolas Brouard   <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
         * imach.c (Module): The use of a Windows BOM (huge) file is now an error          total life expectancy spent in a specific state:
           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
 2021-02-11  Nicolas  Brouard   <brouard@ined.fr>          made the program core dump. It is fixed in this version.
   
         *  (Module): imach.c Someone entered 'results:' instead of 'result:'. Now it is an error which is printed.  2024-04-30  Nicolas Brouard   <brouard@ined.fr>
   
 2020-02-22  Brouard Nicolas  <brouard@ined.fr>          * (Module): In version 0.99s4, we incorporated the calculation of
           the std error of the proportion of total life expectancy spent in
         *  (Module): imach.c Update mle=-3 (for computing Life expectancy          a specific state Var(e.j/e..) using the formula of Var(X/Y)
         and life table from the data without any state)          depending only of the variances of X and Y and expectancies.

         * version.h: Summary: version 0.99.r19          * (Module): This version comes late after having tested
           successfully the praxis C version of Buckhardt.  But Buckardt's
         * imach.c: Summary: Projection syntax simplified          version was difficult to read and Gegenfurtner's version had a few
         We can now start projections, forward or backward, from the mean date          typos which made its results less reliable than Buckhardt's
         of inteviews up to or down to a number of years of projection:          results.  The most important work consisted in retyping the Brent
         prevforecast=1 yearsfproj=15.3 mobil_average=0          original PRAXIS program written in Algol W (published with errors,
         or          ommitting the transposition of matrix V before its QR reduction
         prevforecast=1 starting-proj-date=1/1/2007 final-proj-date=12/31/2017 mobil_average=0          from Golub. I used the recent "awe" compiler from Gkynn Webster.
         or          The awe library had errors, for example in arc tangent function
         prevbackcast=1 yearsbproj=12.3 mobil_average=1          which have been fixed.
         or  
         prevbackcast=1 starting-back-date=1/10/1999 final-back-date=1/1/1985 mobil_average=1          The main objective was to get identical results with the three
           versions: (1) Algol W, (2) Buckhardt'C version as well (3)
 2019-05-18  Brouard Nicolas  <brouard@ined.fr>          Gegenfürtner C versions on the various test functions published by
           Brent in 1973 in Algol W.
         * imach.c: Summary: doxygen tex bug  
           Also, in order to compare them, the random function had to produce
 2019-05-16  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
         * imach.c: Summary: There was some wrong lines added          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
 2019-05-09  Brouard Nicolas  <brouard@ined.fr>          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
         * Makefile, imach.c: *** empty log message ***          seen that authors while trying to mimick original Brent Algol W
           code are hesitating by changing either a loop originally from 1 to
         * ChangeLog: Summary: C=          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: Summary: Some updates          But as IMaCh is using, since the beginning, the Numerical Recipes
           functions vector or matrix, I changed Geggenfürtner code to mimick
         * imach.c: Summary: Before ncovmax          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
         * version.h: *** empty log message ***          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: 0.99r18 unlimited number of individuals          much more problematic in C than in Algol W.  Thus Buckhardt code
         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.          seems very safe, but i haven't chosen it for IMaCh because the C
           style is horrible and almost unreadable compared to Gegenfürtner
 2018-12-13  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
         * imach.c: Summary: Bug for young ages (<-30) will be in r17          minimum of parameters in the functions calls, as it is in Algol
           Brent's code or Gegenfürtner's code, the list of parameters is
 2018-12-05  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
         * Makefile: Summary: 0.99r16          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: Some bugs fixed          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.

           (Module): In order to speed up (in case of numerous covariates) we
           compute health expectancies (without variances) in a first step
         probabilities and covariance matrix          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.
