         *  imach.c (Module): Output of Wald test in the htm file and not only in the log.          * imach.c Version 0.99s5 In fact, the covariance of total life
           expectancy e.. with a partial life expectancy e.j is high,
 2022-05-30  Brouard Nicolas  <brouard@brouard.name>          therefore the complete matrix of variance covariance has to be
           included in the formula of the standard error of the proportion of
         * imach.c: With products of covariates (age or dummies or          total life expectancy spent in a specific state:
         quantitatives), estimates of parameters were good but when          var(X/Y)=mu_x^2/mu_y^2*(sigma_x^2/mu_x^2 -2
         estimating variances the positions of newly created covariates          sigma_xy/mu_x/mu_y+sigma^2/mu_y^2).  Also an error with mle=-3
         were wrongly assigned and results were wrong. Thank to Feinua_Sun!          made the program core dump. It is fixed in this version.

         * imach.c (Module): Some attempts to find a bug of wrong estimates          * (Module): In version 0.99s4, we incorporated the calculation of
         of confidencce intervals with product in the equation modelC          the std error of the proportion of total life expectancy spent in

 2022-05-15  Nicolas Brouard   <brouard@ined.fr>          depending only of the variances of X and Y and expectancies.
   
         * imach.c (Module):  Some minor improvements  2024-04-24  Nicolas Brouard   <brouard@ined.fr>
   
 2022-04-13  Brouard Nicolas  <brouard@brouard.name>          * (Module): This version comes late after having tested
           successfully the praxis C version of Buckhardt.  But Buckardt's
         * imach.c (Module): Adding link to text data files          version was difficult to read and Gegenfurtner's version had a few
           typos which made its results less reliable than Buckhardt's
 2022-04-11  Nicolas Brouard   <brouard@ined.fr>          results.  The most important work consisted in retyping the Brent
           original PRAXIS program written in Algol W (published with errors,
         * imach.c (Module): Error in rewriting the 'r' file with yearsfproj or yearsbproj fixed          ommitting the transposition of matrix V before its QR reduction
           from Golub. I used the recent "awe" compiler from Gkynn Webster.
 2022-04-05  Brouard Nicolas  <brouard@ined.fr>          The awe library had errors, for example in arc tangent function
           which have been fixed.
         * imach.c (Module): Fixed covariates (dummy or quantitative)  
         with missing values have never been allowed but are ERRORS and          The main objective was to get identical results with the three
         program quits. Standard deviations of fixed covariates were          versions: (1) Algol W, (2) Buckhardt'C version as well (3)
         wrongly computed. Mean and standard deviations of time varying          Gegenfürtner C versions on the various test functions published by
         covariates are still not computed.          Brent in 1973 in Algol W.
   
 2022-03-17  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
         * 99r25 Improvements in fixing discrepancies between covariates          imach corresponds to original Brent's random function written in
         missing in result line but in model.          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
 *Wed Mar 31 2021  Nicolas Brouard   <brouard@ined.fr>          real issue in C where, by default, arrays are starting from 0 to
         * imach.c (Module): Still bugs in the result loop. Thank to Holly Benett          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
 *2021-03-08  Nicolas Brouard   <brouard@ined.fr>          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
         * ./ (Module): Fixed bug on result:          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
 *2021-02-20  Nicolas Brouard   <brouard@ined.fr>          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 (Module): Fix bug on quitting after result lines!          x[i] which minimizes the errors. The Golub QR algorithm was
         (Module): Version 0.99r21          published in Algol with overflow errors which were reproduced in
           Brent's Algol W code. Buckhardt code fixed these errors which are
 2021-02-12  Nicolas Brouard   <brouard@ined.fr>          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 (Module): The use of a Windows BOM (huge) file is now an error          style is horrible and almost unreadable compared to Gegenfürtner
           CO code which is very close to Brent's original. Also what makes
           Buckhardt code more difficult to read is, instead of passing the
 2021-02-11  Nicolas  Brouard   <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
         *  (Module): imach.c Someone entered 'results:' instead of 'result:'. Now it is an error which is printed.          high. For example, the flin function LONG REAL PROCEDURE FLIN
           (LONG REAL VALUE L) has only one parameter in Algol W, the
 2020-02-22  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
         *  (Module): imach.c Update mle=-3 (for computing Life expectancy          function has 14 parameters which makes the code unreadable and
         and life table from the data without any state)          useless. Gegenfürtner used a lot of static variables or functions
           which I tried to minimize. Also in Gegefürtner, array dimensions
 2019-05-20  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.
