           included in the formula of the standard error of the proportion of

           * (Module): This version comes late after having tested
         * imach.c: *** empty log message ***          successfully the praxis C version of Buckhardt.  But Buckardt's
           version was difficult to read and Gegenfurtner's version had a few
         * imach.c: Summary: Adding second argument for quitting          typos which made its results less reliable than Buckhardt's
           results.  The most important work consisted in retyping the Brent
 2018-02-21  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          original PRAXIS program written in Algol W (published with errors,
           ommitting the transposition of matrix V before its QR reduction
         * Makefile, README.txt, imach.c: Summary: 0.99r15          from Golub. I used the recent "awe" compiler from Gkynn Webster.
           The awe library had errors, for example in arc tangent function
         New Makefile with recent VirtualBox 5.26. Bug in sqrt negatve in imach.c          which have been fixed.
   
 2017-07-20  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          The main objective was to get identical results with the three
           versions: (1) Algol W, (2) Buckhardt'C version as well (3)
         * imach.c: Summary: temporary working          Gegenfürtner C versions on the various test functions published by
           Brent in 1973 in Algol W.
 2017-07-19  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>  
           Also, in order to compare them, the random function had to produce
         * imach.c: Summary: Bug for mobil_average=0 and prevforecast fixed(?)          the same sequence for the 3 softwares. The random function used in
           imach corresponds to original Brent's random function written in
 2017-07-17  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          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
         * imach.c: Summary: BOM files can be read now          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
 2017-06-30  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          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: Graphs improvements          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: Saito's color          But as IMaCh is using, since the beginning, the Numerical Recipes
           functions vector or matrix, I changed Geggenfürtner code to mimick
 2017-06-29  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          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
         * imach.c: Summary: Version 0.99r14          published in Algol with overflow errors which were reproduced in
           Brent's Algol W code. Buckhardt code fixed these errors which are
 2017-06-27  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          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: More documentation on projections          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: Color of backprojection changed from 6 to 5(yellow)          Buckhardt code more difficult to read is, instead of passing the
           minimum of parameters in the functions calls, as it is in Algol
         * imach.c: Summary: Some bug with rint          Brent's code or Gegenfürtner's code, the list of parameters is
           high. For example, the flin function LONG REAL PROCEDURE FLIN
 2017-05-24  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          (LONG REAL VALUE L) has only one parameter in Algol W, the
           Gegenfürtner flin function had two parameters: static double
         * imach.c: *** empty log message ***          flin(l, j) double l; { int i; double tflin[N];} but Buckhardt
           function has 14 parameters which makes the code unreadable and
 2017-05-23  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          useless. Gegenfürtner used a lot of static variables or functions
           which I tried to minimize. Also in Gegefürtner, array dimensions
         * imach.c: Summary: Code into subroutine, cleanings          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-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.

           contributions to the likelihood is 1 - Prob of dying from last
           health status (= 1-p13= p11+p12 in the easiest case of somebody in
           the healthy state at last known wave). Version is 0.98 
   
   2004-05-20  Brouard Nicolas  <brouard@localhost>
   
           * imach.c (Repository): 
           Agnes added a direct estimation of mortality (without the need of
           computing period prevalence and differential mortality). Thus here
           is version 0.97a which has been distributed to some people at
           REVES 16 in Brugge using an Inno setup.exe for PCs. Estimates of
           mortality using covariates is not done today. Estimating direct
           mortality is a very different process because it doesn't need
           interpolation because it is easy to get the lx from the force of
           the mortality mux in the simplest case as for a Gompertz (log mux
           = a + b*x . But we have been able to incorporate the new code
           within former imach program (0.96d) without deteriorating too much
           the understanding of the program.
