           * imach.c Version 0.99s5 In fact, the covariance of total life
         *  (Module): imach.c Someone entered 'results:' instead of 'result:'. Now it is an error which is printed.          expectancy e.. with a partial life expectancy e.j is high,
           therefore the complete matrix of variance covariance has to be

         and life table from the data without any state)          sigma_xy/mu_x/mu_y+sigma^2/mu_y^2).  Also an error with mle=-3
           made the program core dump. It is fixed in this version.

         or          * (Module): This version comes late after having tested
         prevbackcast=1 yearsbproj=12.3 mobil_average=1          successfully the praxis C version of Buckhardt.  But Buckardt's
         or          version was difficult to read and Gegenfurtner's version had a few
         prevbackcast=1 starting-back-date=1/10/1999 final-back-date=1/1/1985 mobil_average=1          typos which made its results less reliable than Buckhardt's
           results.  The most important work consisted in retyping the Brent
 2019-05-18  Brouard Nicolas  <brouard@ined.fr>          original PRAXIS program written in Algol W (published with errors,
           ommitting the transposition of matrix V before its QR reduction
         * imach.c: Summary: doxygen tex bug          from Golub. I used the recent "awe" compiler from Gkynn Webster.
           The awe library had errors, for example in arc tangent function
 2019-05-16  Brouard Nicolas  <brouard@ined.fr>          which have been fixed.
   
         * imach.c: Summary: There was some wrong lines added          The main objective was to get identical results with the three
           versions: (1) Algol W, (2) Buckhardt'C version as well (3)
 2019-05-09  Brouard Nicolas  <brouard@ined.fr>          Gegenfürtner C versions on the various test functions published by
           Brent in 1973 in Algol W.
         * Makefile, imach.c: *** empty log message ***  
           Also, in order to compare them, the random function had to produce
         * ChangeLog: Summary: C=          the same sequence for the 3 softwares. The random function used in
           imach corresponds to original Brent's random function written in
         * imach.c: Summary: Some updates          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: Before ncovmax          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
         * version.h: *** empty log message ***          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: 0.99r18 unlimited number of individuals          n in a loop from 0 to n-1, or keeping Brent's loop from 1 to n and
         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.          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
 2018-12-13  Brouard Nicolas  <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: Summary: Bug for young ages (<-30) will be in r17          x[i] which minimizes the errors. The Golub QR algorithm was
           published in Algol with overflow errors which were reproduced in
 2018-12-05  Brouard Nicolas  <brouard@ined.fr>          Brent's Algol W code. Buckhardt code fixed these errors which are
           much more problematic in C than in Algol W.  Thus Buckhardt code
         * Makefile: Summary: 0.99r16          seems very safe, but i haven't chosen it for IMaCh because the C
           style is horrible and almost unreadable compared to Gegenfürtner
 2018-05-02  Brouard Nicolas  <brouard@ined.fr>          CO code which is very close to Brent's original. Also what makes
           Buckhardt code more difficult to read is, instead of passing the
         * imach.c: Summary: Some bugs fixed          minimum of parameters in the functions calls, as it is in Algol
           Brent's code or Gegenfürtner's code, the list of parameters is
 2018-05-02  Brouard Nicolas  <brouard@ined.fr>          high. For example, the flin function LONG REAL PROCEDURE FLIN
           (LONG REAL VALUE L) has only one parameter in Algol W, the
         * imach.c:  Summary: Bug for young ages (<-30) will be in r17          Gegenfürtner flin function had two parameters: static double
           flin(l, j) double l; { int i; double tflin[N];} but Buckhardt
 2018-05-02  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: Some bugs fixed          which I tried to minimize. Also in Gegefürtner, array dimensions
           were fixed to N. In my adaptation the flin is static double
 2018-05-01  Brouard Nicolas  <brouard@ined.fr>          flin(double l, int j) and the parameter used are global variables.

           (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

           In the future we should be able to stop the program is only health
           expectancies and graph are needed without standard deviations.
