         * imach.c (Module): Fix bug on quitting after result lines!          * imach.c Version 0.99s5 In fact, the covariance of total life
         (Module): Version 0.99r21          expectancy e.. with a partial life expectancy e.j is high,
           therefore the complete matrix of variance covariance has to be
 2021-02-12  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): The use of a Windows BOM (huge) file is now an error          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
           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.  
           * (Module): In version 0.99s4, we incorporated the calculation of
 2020-02-22  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)
         *  (Module): imach.c Update mle=-3 (for computing Life expectancy          depending only of the variances of X and Y and expectancies.
         and life table from the data without any state)

 2019-05-20  Brouard Nicolas  <brouard@ined.fr>  
           * (Module): This version comes late after having tested
         * version.h: Summary: version 0.99.r19          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: Projection syntax simplified          typos which made its results less reliable than Buckhardt's
         We can now start projections, forward or backward, from the mean date          results.  The most important work consisted in retyping the Brent
         of inteviews up to or down to a number of years of projection:          original PRAXIS program written in Algol W (published with errors,
         prevforecast=1 yearsfproj=15.3 mobil_average=0          ommitting the transposition of matrix V before its QR reduction
         or          from Golub. I used the recent "awe" compiler from Gkynn Webster.
         prevforecast=1 starting-proj-date=1/1/2007 final-proj-date=12/31/2017 mobil_average=0          The awe library had errors, for example in arc tangent function
         or          which have been fixed.
         prevbackcast=1 yearsbproj=12.3 mobil_average=1  
         or          The main objective was to get identical results with the three
         prevbackcast=1 starting-back-date=1/10/1999 final-back-date=1/1/1985 mobil_average=1          versions: (1) Algol W, (2) Buckhardt'C version as well (3)
           Gegenfürtner C versions on the various test functions published by
 2019-05-18  Brouard Nicolas  <brouard@ined.fr>          Brent in 1973 in Algol W.
   
         * imach.c: Summary: doxygen tex bug          Also, in order to compare them, the random function had to produce
           the same sequence for the 3 softwares. The random function used in
 2019-05-16  Brouard Nicolas  <brouard@ined.fr>          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: There was some wrong lines added          '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
 2019-05-09  Brouard Nicolas  <brouard@ined.fr>          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
         * Makefile, imach.c: *** empty log message ***          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
         * ChangeLog: Summary: C=          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 updates          functions vector or matrix, I changed Geggenfürtner code to mimick
           the original Algol W arrays. Thus the X(I) is translated in C as
         * imach.c: Summary: Before ncovmax          x[i] which minimizes the errors. The Golub QR algorithm was
           published in Algol with overflow errors which were reproduced in
         * version.h: *** empty log message ***          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: 0.99r18 unlimited number of individuals          seems very safe, but i haven't chosen it for IMaCh because the C
         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.          style is horrible and almost unreadable compared to Gegenfürtner
           CO code which is very close to Brent's original. Also what makes
 2018-12-13  Brouard Nicolas  <brouard@ined.fr>          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: Bug for young ages (<-30) will be in r17          Brent's code or Gegenfürtner's code, the list of parameters is
           high. For example, the flin function LONG REAL PROCEDURE FLIN
 2018-12-05  Brouard Nicolas  <brouard@ined.fr>          (LONG REAL VALUE L) has only one parameter in Algol W, the
           Gegenfürtner flin function had two parameters: static double
         * Makefile: Summary: 0.99r16          flin(l, j) double l; { int i; double tflin[N];} but Buckhardt
           function has 14 parameters which makes the code unreadable and
 2018-05-02  Brouard Nicolas  <brouard@ined.fr>          useless. Gegenfürtner used a lot of static variables or functions
           which I tried to minimize. Also in Gegefürtner, array dimensions
         * imach.c: Summary: Some bugs fixed          were fixed to N. In my adaptation the flin is static double
           flin(double l, int j) and the parameter used are global variables.
