         * imach.c (Module): Still bugs in the result loop. Thank to Holly Benett          * imach.c (Module): Some bug fixes: in drawings when age*age is
           included in the model as well as with quantitative variables.

   2024-07-02  Nicolas Brouard  <brouard@ined.fr>
         * ./ (Module): Fixed bug on result:  
           * imach.c (Module): Trying compiling on Linux with clang (instead
 2021-02-20  Nicolas Brouard   <brouard@ined.fr>          of gcc which is too slow) and lot of warnings suppressed
   
         * imach.c (Module): Fix bug on quitting after result lines!  2024-06-28  Nicolas Brouard   <brouard@ined.fr>
         (Module): Version 0.99r21  
           * imach.c (Module): fixing some bugs in gnuplot and quantitative
 2021-02-12  Nicolas Brouard   <brouard@ined.fr>          variables, but not completely solved
   
         * imach.c (Module): The use of a Windows BOM (huge) file is now an error  2024-06-28  Nicolas Brouard  <brouard@ined.fr>

   2024-05-12  Nicolas Brouard   <brouard@ined.fr>
         *  (Module): imach.c Someone entered 'results:' instead of 'result:'. Now it is an error which is printed.  
           * imach.c Version 0.99s5 In fact, the covariance of total life
 2020-02-22  Brouard Nicolas  <brouard@ined.fr>          expectancy e.. with a partial life expectancy e.j is high,
           therefore the complete matrix of variance covariance has to be
         *  (Module): imach.c Update mle=-3 (for computing Life expectancy          included in the formula of the standard error of the proportion of
         and life table from the data without any state)          total life expectancy spent in a specific state:
           var(X/Y)=mu_x^2/mu_y^2*(sigma_x^2/mu_x^2 -2
 2019-05-20  Brouard Nicolas  <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.
         * version.h: Summary: version 0.99.r19  
   2024-04-30  Nicolas Brouard   <brouard@ined.fr>
         * imach.c: Summary: Projection syntax simplified  
         We can now start projections, forward or backward, from the mean date          * (Module): In version 0.99s4, we incorporated the calculation of
         of inteviews up to or down to a number of years of projection:          the std error of the proportion of total life expectancy spent in
         prevforecast=1 yearsfproj=15.3 mobil_average=0          a specific state Var(e.j/e..) using the formula of Var(X/Y)
         or          depending only of the variances of X and Y and expectancies.

         or          * (Module): This version comes late after having tested
         prevbackcast=1 starting-back-date=1/10/1999 final-back-date=1/1/1985 mobil_average=1          successfully the praxis C version of Buckhardt.  But Buckardt's
           version was difficult to read and Gegenfurtner's version had a few
 2019-05-18  Brouard Nicolas  <brouard@ined.fr>          typos which made its results less reliable than Buckhardt's
           results.  The most important work consisted in retyping the Brent
         * imach.c: Summary: doxygen tex bug          original PRAXIS program written in Algol W (published with errors,
           ommitting the transposition of matrix V before its QR reduction
 2019-05-16  Brouard Nicolas  <brouard@ined.fr>          from Golub. I used the recent "awe" compiler from Gkynn Webster.
           The awe library had errors, for example in arc tangent function
         * imach.c: Summary: There was some wrong lines added          which have been fixed.
   
 2019-05-09  Brouard Nicolas  <brouard@ined.fr>          The main objective was to get identical results with the three
           versions: (1) Algol W, (2) Buckhardt'C version as well (3)
         * Makefile, imach.c: *** empty log message ***          Gegenfürtner C versions on the various test functions published by
           Brent in 1973 in Algol W.
         * ChangeLog: Summary: C=  
           Also, in order to compare them, the random function had to produce
         * imach.c: Summary: Some updates          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: Before ncovmax          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
         * version.h: *** empty log message ***          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: 0.99r18 unlimited number of individuals          seen that authors while trying to mimick original Brent Algol W
         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.          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
 2018-12-13  Brouard Nicolas  <brouard@ined.fr>          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: Bug for young ages (<-30) will be in r17          functions vector or matrix, I changed Geggenfürtner code to mimick
           the original Algol W arrays. Thus the X(I) is translated in C as
 2018-12-05  Brouard Nicolas  <brouard@ined.fr>          x[i] which minimizes the errors. The Golub QR algorithm was
           published in Algol with overflow errors which were reproduced in
         * Makefile: Summary: 0.99r16          Brent's Algol W code. Buckhardt code fixed these errors which are
           much more problematic in C than in Algol W.  Thus Buckhardt code
 2018-05-02  Brouard Nicolas  <brouard@ined.fr>          seems very safe, but i haven't chosen it for IMaCh because the C
           style is horrible and almost unreadable compared to Gegenfürtner
         * imach.c: Summary: Some bugs fixed          CO code which is very close to Brent's original. Also what makes
           Buckhardt code more difficult to read is, instead of passing the
 2018-05-02  Brouard Nicolas  <brouard@ined.fr>          minimum of parameters in the functions calls, as it is in Algol
           Brent's code or Gegenfürtner's code, the list of parameters is
         * imach.c:  Summary: Bug for young ages (<-30) will be in r17          high. For example, the flin function LONG REAL PROCEDURE FLIN
           (LONG REAL VALUE L) has only one parameter in Algol W, the
 2018-05-02  Brouard Nicolas  <brouard@ined.fr>          Gegenfürtner flin function had two parameters: static double
           flin(l, j) double l; { int i; double tflin[N];} but Buckhardt
         * imach.c: Summary: Some bugs fixed          function has 14 parameters which makes the code unreadable and
           useless. Gegenfürtner used a lot of static variables or functions
 2018-05-01  Brouard Nicolas  <brouard@ined.fr>          which I tried to minimize. Also in Gegefürtner, array dimensions
           were fixed to N. In my adaptation the flin is static double
         * imach.c:          flin(double l, int j) and the parameter used are global variables.
         Summary: Bug fixed by providing frequencies only for non missing covariates

 2018-04-27  Brouard Nicolas  <brouard@ined.fr>

 2018-02-21  Brouard Nicolas  <brouard@ined.fr>          * imach.c (Module): Version 0.99r42 needed a newer version of

           (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.
