         * imach.c (Module): Still bugs in the result loop. Thank to Holly Benett  
           * imach.c Version 0.99s5 In fact, the covariance of total life
 *2021-03-08  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
         * ./ (Module): Fixed bug on result:          included in the formula of the standard error of the proportion of
           total life expectancy spent in a specific state:
 *2021-02-20  Nicolas Brouard   <brouard@ined.fr>          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 (Module): Fix bug on quitting after result lines!          made the program core dump. It is fixed in this version.
         (Module): Version 0.99r21

         * imach.c (Module): The use of a Windows BOM (huge) file is now an error          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)
           depending only of the variances of X and Y and expectancies.

         *  (Module): imach.c Someone entered 'results:' instead of 'result:'. Now it is an error which is printed.  
           * (Module): This version comes late after having tested
 2020-02-22  Brouard Nicolas  <brouard@ined.fr>          successfully the praxis C version of Buckhardt.  But Buckardt's
           version was difficult to read and Gegenfurtner's version had a few
         *  (Module): imach.c Update mle=-3 (for computing Life expectancy          typos which made its results less reliable than Buckhardt's
         and life table from the data without any state)          results.  The most important work consisted in retyping the Brent
           original PRAXIS program written in Algol W (published with errors,
 2019-05-20  Brouard Nicolas  <brouard@ined.fr>          ommitting the transposition of matrix V before its QR reduction
           from Golub. I used the recent "awe" compiler from Gkynn Webster.
         * version.h: Summary: version 0.99.r19          The awe library had errors, for example in arc tangent function
           which have been fixed.
         * imach.c: Summary: Projection syntax simplified  
         We can now start projections, forward or backward, from the mean date          The main objective was to get identical results with the three
         of inteviews up to or down to a number of years of projection:          versions: (1) Algol W, (2) Buckhardt'C version as well (3)
         prevforecast=1 yearsfproj=15.3 mobil_average=0          Gegenfürtner C versions on the various test functions published by
         or          Brent in 1973 in Algol W.
         prevforecast=1 starting-proj-date=1/1/2007 final-proj-date=12/31/2017 mobil_average=0  
         or          Also, in order to compare them, the random function had to produce
         prevbackcast=1 yearsbproj=12.3 mobil_average=1          the same sequence for the 3 softwares. The random function used in
         or          imach corresponds to original Brent's random function written in
         prevbackcast=1 starting-back-date=1/10/1999 final-back-date=1/1/1985 mobil_average=1          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
 2019-05-18  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
         * imach.c: Summary: doxygen tex bug          seen that authors while trying to mimick original Brent Algol W
           code are hesitating by changing either a loop originally from 1 to
 2019-05-16  Brouard Nicolas  <brouard@ined.fr>          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: There was some wrong lines added          But as IMaCh is using, since the beginning, the Numerical Recipes
           functions vector or matrix, I changed Geggenfürtner code to mimick
 2019-05-09  Brouard Nicolas  <brouard@ined.fr>          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
         * Makefile, imach.c: *** 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
         * ChangeLog: Summary: C=          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
         * imach.c: Summary: Some updates          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: Before ncovmax          Buckhardt code more difficult to read is, instead of passing the
           minimum of parameters in the functions calls, as it is in Algol
         * version.h: *** empty log message ***          Brent's code or Gegenfürtner's code, the list of parameters is
           high. For example, the flin function LONG REAL PROCEDURE FLIN
         * imach.c: Summary: 0.99r18 unlimited number of individuals          (LONG REAL VALUE L) has only one parameter in Algol W, the
         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.          Gegenfürtner flin function had two parameters: static double
           flin(l, j) double l; { int i; double tflin[N];} but Buckhardt
 2018-12-13  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: Bug for young ages (<-30) will be in r17          which I tried to minimize. Also in Gegefürtner, array dimensions
           were fixed to N. In my adaptation the flin is static double
 2018-12-05  Brouard Nicolas  <brouard@ined.fr>          flin(double l, int j) and the parameter used are global variables.

         * imach.c: *** empty log message ***          * imach.c (Module): Version 0.99r33 A lot of changes in
           reassigning covariates: my first idea was that people will always
 2017-05-23  Brouard Nicolas  <brouard@ined.fr>          use the first covariate V1 into the model but in fact they are
           producing data with many covariates and can use an equation model
