         *  (Module): imach.c Update mle=-3 (for computing Life expectancy          * imach.c Version 0.99s5 In fact, the covariance of total life
         and life table from the data without any state)          expectancy e.. with a partial life expectancy e.j is high,
           therefore the complete matrix of variance covariance has to be
 2019-05-20  Brouard Nicolas  <brouard@brouard.name>          included in the formula of the standard error of the proportion of
           total life expectancy spent in a specific state:
         * version.h: Summary: version 0.99.r19          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: Summary: Projection syntax simplified          made the program core dump. It is fixed in this version.
         We can now start projections, forward or backward, from the mean date  
         of inteviews up to or down to a number of years of projection:  2024-04-30  Nicolas Brouard   <brouard@ined.fr>
         prevforecast=1 yearsfproj=15.3 mobil_average=0  
         or          * (Module): In version 0.99s4, we incorporated the calculation of
         prevforecast=1 starting-proj-date=1/1/2007 final-proj-date=12/31/2017 mobil_average=0          the std error of the proportion of total life expectancy spent in
         or          a specific state Var(e.j/e..) using the formula of Var(X/Y)
         prevbackcast=1 yearsbproj=12.3 mobil_average=1          depending only of the variances of X and Y and expectancies.

 2019-05-18  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: Summary: doxygen tex bug          version was difficult to read and Gegenfurtner's version had a few
           typos which made its results less reliable than Buckhardt's
 2019-05-16  Brouard Nicolas  <brouard@brouard.name>          results.  The most important work consisted in retyping the Brent
           original PRAXIS program written in Algol W (published with errors,
         * imach.c: Summary: There was some wrong lines added          ommitting the transposition of matrix V before its QR reduction
           from Golub. I used the recent "awe" compiler from Gkynn Webster.
 2019-05-09  Brouard Nicolas  <brouard@brouard.name>          The awe library had errors, for example in arc tangent function
           which have been fixed.
         * Makefile, imach.c: *** empty log message ***  
           The main objective was to get identical results with the three
         * ChangeLog: Summary: C=          versions: (1) Algol W, (2) Buckhardt'C version as well (3)
           Gegenfürtner C versions on the various test functions published by
         * imach.c: Summary: Some updates          Brent in 1973 in Algol W.
   
         * imach.c: Summary: Before ncovmax          Also, in order to compare them, the random function had to produce
           the same sequence for the 3 softwares. The random function used in
         * version.h: *** empty log message ***          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: 0.99r18 unlimited number of individuals          'normal' mathematical arrays starting from 1 to n. But this is a
         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.          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
 2018-12-13  Brouard Nicolas  <brouard@brouard.name>          seen that authors while trying to mimick original Brent Algol W
           code are hesitating by changing either a loop originally from 1 to
         * imach.c: Summary: Bug for young ages (<-30) will be in r17          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.
 2018-12-05  Brouard Nicolas  <brouard@brouard.name>          But as IMaCh is using, since the beginning, the Numerical Recipes
           functions vector or matrix, I changed Geggenfürtner code to mimick
         * Makefile: Summary: 0.99r16          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
 2018-05-02  Brouard Nicolas  <brouard@brouard.name>          published in Algol with overflow errors which were reproduced in
           Brent's Algol W code. Buckhardt code fixed these errors which are
         * imach.c: Summary: Some bugs fixed          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
 2018-05-02  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          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
 2018-05-02  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          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: Some bugs fixed          (LONG REAL VALUE L) has only one parameter in Algol W, the
           Gegenfürtner flin function had two parameters: static double
 2018-05-01  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          flin(l, j) double l; { int i; double tflin[N];} but Buckhardt
           function has 14 parameters which makes the code unreadable and
         * imach.c:          useless. Gegenfürtner used a lot of static variables or functions
         Summary: Bug fixed by providing frequencies only for non missing covariates          which I tried to minimize. Also in Gegefürtner, array dimensions
           were fixed to N. In my adaptation the flin is static double
 2018-04-27  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          flin(double l, int j) and the parameter used are global variables.

           * imach.c (Module): Yes the sum of survivors was wrong since
           imach-114 because nhstepm was no more computed in the age
           loop. Now we define nhstepma in the age loop.
           (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.
