         * imach.c (Module): Still bugs in the result loop. Thank to Holly Benett  
           * imach.c (Module): Trying compiling on Linux with clang (instead
 *2021-03-08  Nicolas Brouard   <brouard@ined.fr>          of gcc which is too slow) and lot of warnings suppressed
   
         * ./ (Module): Fixed bug on result:  2024-06-28  Nicolas Brouard  <brouard@ined.fr>
   
 *2021-02-20  Nicolas Brouard   <brouard@ined.fr>          * imach.c (Module): s6 errors with age*age (harmless).
   
         * imach.c (Module): Fix bug on quitting after result lines!  2024-05-12  Nicolas Brouard   <brouard@ined.fr>
         (Module): Version 0.99r21  
           * imach.c Version 0.99s5 In fact, the covariance of total life
 2021-02-12  Nicolas Brouard   <brouard@ined.fr>          expectancy e.. with a partial life expectancy e.j is high,
           therefore the complete matrix of variance covariance has to be
         * imach.c (Module): The use of a Windows BOM (huge) file is now an error          included in the formula of the standard error of the proportion of
           total life expectancy spent in a specific state:
           var(X/Y)=mu_x^2/mu_y^2*(sigma_x^2/mu_x^2 -2
 2021-02-11  Nicolas  Brouard   <brouard@ined.fr>          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.  
   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
         *  (Module): imach.c Update mle=-3 (for computing Life expectancy          the std error of the proportion of total life expectancy spent in
         and life table from the data without any state)          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.

         * version.h: Summary: version 0.99.r19  
           * (Module): This version comes late after having tested
         * imach.c: Summary: Projection syntax simplified          successfully the praxis C version of Buckhardt.  But Buckardt's
         We can now start projections, forward or backward, from the mean date          version was difficult to read and Gegenfurtner's version had a few
         of inteviews up to or down to a number of years of projection:          typos which made its results less reliable than Buckhardt's
         prevforecast=1 yearsfproj=15.3 mobil_average=0          results.  The most important work consisted in retyping the Brent
         or          original PRAXIS program written in Algol W (published with errors,
         prevforecast=1 starting-proj-date=1/1/2007 final-proj-date=12/31/2017 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.
         prevbackcast=1 yearsbproj=12.3 mobil_average=1          The awe library had errors, for example in arc tangent function
         or          which have been fixed.
         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
 2019-05-18  Brouard Nicolas  <brouard@ined.fr>          versions: (1) Algol W, (2) Buckhardt'C version as well (3)
           Gegenfürtner C versions on the various test functions published by
         * imach.c: Summary: doxygen tex bug          Brent in 1973 in Algol W.
   
 2019-05-16  Brouard Nicolas  <brouard@ined.fr>          Also, in order to compare them, the random function had to produce
           the same sequence for the 3 softwares. The random function used in
         * imach.c: Summary: There was some wrong lines added          imach corresponds to original Brent's random function written in
           Algol W.  Other point, in Algol W, the arrays of dimension n are
 2019-05-09  Brouard Nicolas  <brouard@ined.fr>          '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
         * Makefile, imach.c: *** empty log message ***          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
         * ChangeLog: Summary: C=          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
         * imach.c: Summary: Some updates          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: Before ncovmax          functions vector or matrix, I changed Geggenfürtner code to mimick
           the original Algol W arrays. Thus the X(I) is translated in C as
         * version.h: *** empty log message ***          x[i] which minimizes the errors. The Golub QR algorithm was
           published in Algol with overflow errors which were reproduced in
         * imach.c: Summary: 0.99r18 unlimited number of individuals          Brent's Algol W code. Buckhardt code fixed these errors which are
         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.          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
 2018-12-13  Brouard Nicolas  <brouard@ined.fr>          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: Bug for young ages (<-30) will be in r17          Buckhardt code more difficult to read is, instead of passing the
           minimum of parameters in the functions calls, as it is in Algol
 2018-12-05  Brouard Nicolas  <brouard@ined.fr>          Brent's code or Gegenfürtner's code, the list of parameters is
           high. For example, the flin function LONG REAL PROCEDURE FLIN
         * Makefile: Summary: 0.99r16          (LONG REAL VALUE L) has only one parameter in Algol W, the
           Gegenfürtner flin function had two parameters: static double
 2018-05-02  Brouard Nicolas  <brouard@ined.fr>          flin(l, j) double l; { int i; double tflin[N];} but Buckhardt
           function has 14 parameters which makes the code unreadable and
         * imach.c: Summary: Some bugs fixed          useless. Gegenfürtner used a lot of static variables or functions
           which I tried to minimize. Also in Gegefürtner, array dimensions
 2018-05-02  Brouard Nicolas  <brouard@ined.fr>          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: Bug for young ages (<-30) will be in r17

         Summary: backprojection and confidence intervals of backprevalence          * imach.c (Module): Version 0.99r33 A lot of changes in

 2017-04-26  Brouard Nicolas  <brouard@ined.fr>          and the combination for V2 should be codtabm(k,1) instead of
