           therefore the complete matrix of variance covariance has to be

         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.          version was difficult to read and Gegenfurtner's version had a few
           typos which made its results less reliable than Buckhardt's
 2018-12-13  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: Bug for young ages (<-30) will be in r17          ommitting the transposition of matrix V before its QR reduction
           from Golub. I used the recent "awe" compiler from Gkynn Webster.
 2018-12-05  Brouard Nicolas  <brouard@brouard.name>          The awe library had errors, for example in arc tangent function
           which have been fixed.
         * Makefile: Summary: 0.99r16  
           The main objective was to get identical results with the three
 2018-05-02  Brouard Nicolas  <brouard@brouard.name>          versions: (1) Algol W, (2) Buckhardt'C version as well (3)
           Gegenfürtner C versions on the various test functions published by

 2018-05-02  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          Also, in order to compare them, the random function had to produce
           the same sequence for the 3 softwares. The random function used in

 2018-05-02  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          'normal' mathematical arrays starting from 1 to n. But this is a
           real issue in C where, by default, arrays are starting from 0 to
         * imach.c: Summary: Some bugs fixed          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
 2018-05-01  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          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
         * imach.c:          shifting the index from original X(I) in Algol W to x[i-1] in C.
         Summary: Bug fixed by providing frequencies only for non missing covariates          But as IMaCh is using, since the beginning, the Numerical Recipes
           functions vector or matrix, I changed Geggenfürtner code to mimick
 2018-04-27  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: some minor bugs          published in Algol with overflow errors which were reproduced in
           Brent's Algol W code. Buckhardt code fixed these errors which are
 2018-04-21  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
         * README.txt: *** empty log message ***          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: Some bugs fixed, valgrind tested          Buckhardt code more difficult to read is, instead of passing the
           minimum of parameters in the functions calls, as it is in Algol
 2018-04-20  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
         * Makefile, README.txt, setup.iss: Summary: imach 0.99r16          (LONG REAL VALUE L) has only one parameter in Algol W, the

         Summary: Computing mean and stdeviation of fixed quantitative variables          function has 14 parameters which makes the code unreadable and
           useless. Gegenfürtner used a lot of static variables or functions
 2018-04-19  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          which I tried to minimize. Also in Gegefürtner, array dimensions
           were fixed to N. In my adaptation the flin is static double

           (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.
