         * imach.c (Module): Fix bug on quitting after result lines!          * imach.c (Module): Trying compiling on Linux with clang (instead
         (Module): Version 0.99r21          of gcc which is too slow) and lot of warnings suppressed

           * imach.c (Module): s6 errors with age*age (harmless).
         *  (Module): imach.c Someone entered 'results:' instead of 'result:'. Now it is an error which is printed.  
   2024-05-12  Nicolas Brouard   <brouard@ined.fr>
 2020-02-22  Brouard Nicolas  <brouard@ined.fr>  
           * imach.c Version 0.99s5 In fact, the covariance of total life
         *  (Module): imach.c Update mle=-3 (for computing Life expectancy          expectancy e.. with a partial life expectancy e.j is high,
         and life table from the data without any state)          therefore the complete matrix of variance covariance has to be
           included in the formula of the standard error of the proportion of
 2019-05-20  Brouard Nicolas  <brouard@ined.fr>          total life expectancy spent in a specific state:
           var(X/Y)=mu_x^2/mu_y^2*(sigma_x^2/mu_x^2 -2
         * version.h: Summary: version 0.99.r19          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.
         * imach.c: Summary: Projection syntax simplified  
         We can now start projections, forward or backward, from the mean date  2024-04-30  Nicolas Brouard   <brouard@ined.fr>
         of inteviews up to or down to a number of years of projection:  
         prevforecast=1 yearsfproj=15.3 mobil_average=0          * (Module): In version 0.99s4, we incorporated the calculation of
         or          the std error of the proportion of total life expectancy spent in
         prevforecast=1 starting-proj-date=1/1/2007 final-proj-date=12/31/2017 mobil_average=0          a specific state Var(e.j/e..) using the formula of Var(X/Y)
         or          depending only of the variances of X and Y and expectancies.
         prevbackcast=1 yearsbproj=12.3 mobil_average=1  
         or  2024-04-24  Nicolas Brouard   <brouard@ined.fr>
         prevbackcast=1 starting-back-date=1/10/1999 final-back-date=1/1/1985 mobil_average=1  
           * (Module): This version comes late after having tested
 2019-05-18  Brouard Nicolas  <brouard@ined.fr>          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: doxygen tex bug          typos which made its results less reliable than Buckhardt's
           results.  The most important work consisted in retyping the Brent
 2019-05-16  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: There was some wrong lines added          from Golub. I used the recent "awe" compiler from Gkynn Webster.
           The awe library had errors, for example in arc tangent function
 2019-05-09  Brouard Nicolas  <brouard@ined.fr>          which have been fixed.
   
         * Makefile, imach.c: *** empty log message ***          The main objective was to get identical results with the three
           versions: (1) Algol W, (2) Buckhardt'C version as well (3)
         * ChangeLog: Summary: C=          Gegenfürtner C versions on the various test functions published by
           Brent in 1973 in Algol W.
         * imach.c: Summary: Some updates  
           Also, in order to compare them, the random function had to produce
         * imach.c: Summary: Before ncovmax          the same sequence for the 3 softwares. The random function used in
           imach corresponds to original Brent's random function written in
         * version.h: *** empty log message ***          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: 0.99r18 unlimited number of individuals          real issue in C where, by default, arrays are starting from 0 to
         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.          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
 2018-12-13  Brouard Nicolas  <brouard@ined.fr>          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: Bug for young ages (<-30) will be in r17          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
 2018-12-05  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
         * Makefile: Summary: 0.99r16          x[i] which minimizes the errors. The Golub QR algorithm was
           published in Algol with overflow errors which were reproduced in
 2018-05-02  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
         * imach.c: Summary: Some bugs fixed          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: Bug for young ages (<-30) will be in r17          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: Some bugs fixed          Gegenfürtner flin function had two parameters: static double
           flin(l, j) double l; { int i; double tflin[N];} but Buckhardt
 2018-05-01  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:          which I tried to minimize. Also in Gegefürtner, array dimensions
         Summary: Bug fixed by providing frequencies only for non missing covariates          were fixed to N. In my adaptation the flin is static double
           flin(double l, int j) and the parameter used are global variables.

         introduced the exact date of death then we should have modified

         mortality artificially. The bad side is that we add another loop  
           * imach.c (Module): Merging 1.61 to 1.162
   
         which slows down the processing. The difference can be up to 10%  2014-09-02  Nicolas J Brouard   <nbrouard@njbrouard.ined.fr>

   2006-04-28  Brouard Nicolas  <brouard@localhost>
   
           * 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.

   2003-06-14  Brouard Nicolas  <brouard@homebrou>

           the contribution of an exact death to the likelihood. This new
           contribution is smaller and very dependent of the step unit
           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.
