+   Revision 1.140  2011/09/02 10:37:54  brouard
+   Summary: times.h is ok with mingw32 now.
+   Revision 1.139  2010/06/14 07:50:17  brouard
+   After the theft of my laptop, I probably lost some lines of codes which were not uploaded to the CVS tree.
+   I remember having already fixed agemin agemax which are pointers now but not cvs saved.
+   Revision 1.138  2010/04/30 18:19:40  brouard
+   *** empty log message ***
+   Revision 1.137  2010/04/29 18:11:38  brouard
+   (Module): Checking covariates for more complex models
+   than V1+V2. A lot of change to be done. Unstable.
+   Revision 1.136  2010/04/26 20:30:53  brouard
+   (Module): merging some libgsl code. Fixing computation
+   of likelione (using inter/intrapolation if mle = 0) in order to
+   get same likelihood as if mle=1.
+   Some cleaning of code and comments added.
+   Revision 1.135  2009/10/29 15:33:14  brouard
+   (Module): Now imach stops if date of birth, at least year of birth, is not given. Some cleaning of the code.
+   Revision 1.134  2009/10/29 13:18:53  brouard
+   (Module): Now imach stops if date of birth, at least year of birth, is not given. Some cleaning of the code.
+   Revision 1.133  2009/07/06 10:21:25  brouard
+   just nforces
+   Revision 1.132  2009/07/06 08:22:05  brouard
+   Many tings
+   Revision 1.131  2009/06/20 16:22:47  brouard
+   Some dimensions resccaled
+   Revision 1.130  2009/05/26 06:44:34  brouard
+   (Module): Max Covariate is now set to 20 instead of 8. A
+   lot of cleaning with variables initialized to 0. Trying to make
+   V2+V3*age+V1+V4 strb=V3*age+V1+V4 working better.
+   Revision 1.129  2007/08/31 13:49:27  lievre
+   Modification of the way of exiting when the covariate is not binary in order to see on the window the error message before exiting
+   Revision 1.128  2006/06/30 13:02:05  brouard
+   (Module): Clarifications on computing e.j
+   Revision 1.127  2006/04/28 18:11:50  brouard
+   (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.
+   Revision 1.126  2006/04/28 17:23:28  brouard
+   (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): sump fixed, loop imx fixed, and simplifications.
+   (Module): If the status is missing at the last wave but we know
+   that the person is alive, then we can code his/her status as -2
+   (instead of missing=-1 in earlier versions) and his/her
+   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
+   Revision 1.103  2005/09/30 15:54:49  lievre

+   Revision 1.99  2004/06/05 08:57:40  brouard
+   *** empty log message ***
+   Revision 1.98  2004/05/16 15:05:56  brouard
+   New version 0.97 . First attempt to estimate force of mortality
+   directly from the data i.e. without the need of knowing the health
+   state at each age, but using a Gompertz model: log u =a + b*age .
+   This is the basic analysis of mortality and should be done before any
+   other analysis, in order to test if the mortality estimated from the
+   cross-longitudinal survey is different from the mortality estimated
+   from other sources like vital statistic data.
+   The same imach parameter file can be used but the option for mle should be -3.
+   Agnès, who wrote this part of the code, tried to keep most of the
+   former routines in order to include the new code within the former code.
+   The output is very simple: only an estimate of the intercept and of
+   the slope with 95% confident intervals.
+   Current limitations:
+   A) Even if you enter covariates, i.e. with the
+   model= V1+V2 equation for example, the programm does only estimate a unique global model without covariates.
+   B) There is no computation of Life Expectancy nor Life Table.
+   Revision 1.97  2004/02/20 13:25:42  lievre
+   Version 0.96d. Population forecasting command line is (temporarily)
+   suppressed.
+   Revision 1.96  2003/07/15 15:38:55  brouard
+   * imach.c (Repository): Errors in subdirf, 2, 3 while printing tmpout is
+   rewritten within the same printf. Workaround: many printfs.
+   Revision 1.95  2003/07/08 07:54:34  brouard
+   * imach.c (Repository):
+   (Repository): Using imachwizard code to output a more meaningful covariance
+   matrix (cov(a12,c31) instead of numbers.
+   Revision 1.94  2003/06/27 13:00:02  brouard
+   Just cleaning
+   Revision 1.93  2003/06/25 16:33:55  brouard
+   (Module): On windows (cygwin) function asctime_r doesn't
+   exist so I changed back to asctime which exists.
+   (Module): Version 0.96b
+   Revision 1.92  2003/06/25 16:30:45  brouard
+   (Module): On windows (cygwin) function asctime_r doesn't
+   exist so I changed back to asctime which exists.
+   Revision 1.91  2003/06/25 15:30:29  brouard
+   * imach.c (Repository): Duplicated warning errors corrected.
+   (Repository): Elapsed time after each iteration is now output. It
+   helps to forecast when convergence will be reached. Elapsed time
+   is stamped in powell.  We created a new html file for the graphs
+   concerning matrix of covariance. It has extension -cov.htm.
+   Revision 1.90  2003/06/24 12:34:15  brouard
+   (Module): Some bugs corrected for windows. Also, when
+   mle=-1 a template is output in file "or"mypar.txt with the design
+   of the covariance matrix to be input.
+   Revision 1.89  2003/06/24 12:30:52  brouard
+   (Module): Some bugs corrected for windows. Also, when
+   mle=-1 a template is output in file "or"mypar.txt with the design
+   of the covariance matrix to be input.
+   Revision 1.88  2003/06/23 17:54:56  brouard
+   * imach.c (Repository): Create a sub-directory where all the secondary files are. Only imach, htm, gp and r(imach) are on the main directory. Correct time and other things.
+   Revision 1.87  2003/06/18 12:26:01  brouard
+   Version 0.96
+   Revision 1.86  2003/06/17 20:04:08  brouard
+   (Module): Change position of html and gnuplot routines and added
+   routine fileappend.
+   Revision 1.85  2003/06/17 13:12:43  brouard
+   * imach.c (Repository): Check when date of death was earlier that
+   current date of interview. It may happen when the death was just
+   prior to the death. In this case, dh was negative and likelihood
+   was wrong (infinity). We still send an "Error" but patch by
+   assuming that the date of death was just one stepm after the
+   interview.
+   (Repository): Because some people have very long ID (first column)
+   we changed int to long in num[] and we added a new lvector for
+   memory allocation. But we also truncated to 8 characters (left
+   truncation)
+   (Repository): No more line truncation errors.
+   Revision 1.84  2003/06/13 21:44:43  brouard
+   * imach.c (Repository): Replace "freqsummary" at a correct
+   place. It differs from routine "prevalence" which may be called
+   many times. Probs is memory consuming and must be used with
+   parcimony.
+   Version 0.95a3 (should output exactly the same maximization than 0.8a2)
+   Revision 1.83  2003/06/10 13:39:11  lievre
+   *** empty log message ***
+   Revision 1.82  2003/06/05 15:57:20  brouard
+   Add log in  imach.c and  fullversion number is now printed.

    Short summary of the programme:

    hPijx is the probability to be observed in state i at age x+h

    matrix is simply the matrix product of nh*stepm elementary matrices
    and the contribution of each individual to the likelihood is simply
    hPijx.
