         *  (Module): imach.c Someone entered 'results:' instead of 'result:'. Now it is an error which is printed.          * imach.c (Module): Some bug fixes: in drawings when age*age is
           included in the model as well as with quantitative variables.

         *  (Module): imach.c Update mle=-3 (for computing Life expectancy  
         and life table from the data without any state)          * imach.c (Module): Trying compiling on Linux with clang (instead
           of gcc which is too slow) and lot of warnings suppressed

           * imach.c (Module): fixing some bugs in gnuplot and quantitative
         * imach.c: Summary: Projection syntax simplified          variables, but not completely solved
         We can now start projections, forward or backward, from the mean date

 2019-05-09  Brouard Nicolas  <brouard@brouard.name>          * (Module): In version 0.99s4, we incorporated the calculation of

         * imach.c: Summary: Some updates  
           * (Module): This version comes late after having tested
         * imach.c: Summary: Before ncovmax          successfully the praxis C version of Buckhardt.  But Buckardt's
           version was difficult to read and Gegenfurtner's version had a few
         * version.h: *** empty log message ***          typos which made its results less reliable than Buckhardt's
           results.  The most important work consisted in retyping the Brent
         * imach.c: Summary: 0.99r18 unlimited number of individuals          original PRAXIS program written in Algol W (published with errors,
         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.          ommitting the transposition of matrix V before its QR reduction
           from Golub. I used the recent "awe" compiler from Gkynn Webster.
 2018-12-13  Brouard Nicolas  <brouard@brouard.name>          The awe library had errors, for example in arc tangent function
           which have been fixed.
         * imach.c: Summary: Bug for young ages (<-30) will be in r17  
           The main objective was to get identical results with the three
 2018-12-05  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
         * Makefile: Summary: 0.99r16          Brent in 1973 in Algol W.
   
 2018-05-02  Brouard Nicolas  <brouard@brouard.name>          Also, in order to compare them, the random function had to produce
           the same sequence for the 3 softwares. The random function used in
         * imach.c: Summary: Some bugs fixed          imach corresponds to original Brent's random function written in
           Algol W.  Other point, in Algol W, the arrays of dimension n are
 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: Bug for young ages (<-30) will be in r17          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
 2018-05-02  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: Summary: Some bugs fixed          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
 2018-05-01  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          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:          x[i] which minimizes the errors. The Golub QR algorithm was
         Summary: Bug fixed by providing frequencies only for non missing covariates          published in Algol with overflow errors which were reproduced in
           Brent's Algol W code. Buckhardt code fixed these errors which are
 2018-04-27  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: some minor bugs          style is horrible and almost unreadable compared to Gegenfürtner
           CO code which is very close to Brent's original. Also what makes
 2018-04-21  Brouard Nicolas  <brouard@brouard-antoine.homelinux.com>          Buckhardt code more difficult to read is, instead of passing the
           minimum of parameters in the functions calls, as it is in Algol
         * README.txt: *** empty log message ***          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, valgrind tested          (LONG REAL VALUE L) has only one parameter in Algol W, the
           Gegenfürtner flin function had two parameters: static double
 2018-04-20  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
         * Makefile, README.txt, setup.iss: Summary: imach 0.99r16          useless. Gegenfürtner used a lot of static variables or functions
           which I tried to minimize. Also in Gegefürtner, array dimensions
         * imach.c:          were fixed to N. In my adaptation the flin is static double
         Summary: Computing mean and stdeviation of fixed quantitative variables          flin(double l, int j) and the parameter used are global variables.

           stepm. It is no more the probability to die between last interview
           and month of death but the probability to survive from last
           interview up to one month before death multiplied by the
           probability to die within a month. Thanks to Chris
           Jackson for correcting this bug.  Former versions increased
           mortality artificially. The bad side is that we add another loop
           which slows down the processing. The difference can be up to 10%
           lower mortality.
