         * imach.c: Some cleaning          * imach.c (Repository): Check when date of death was earlier that
 2003-03-28    <brouard@BROUARD>          current date of interview. It may happen when the death was just
           prior to the death. In this case, dh was negative and likelihood
         * imach.c (Module): In version up to 0.92 likelihood was computed          was wrong (infinity). We still send an "Error" but patch by
         as if date of death was unknown. Death was treated as any other          assuming that the date of death was just one stepm after the
         health state: the date of the interview describes the actual state          interview.
         and not the date of a change in health state. The former idea was          (Repository): Because some people have very long ID (first column)
         to consider that at each interview the state was recorded          we changed int to long in num[] and we added a new lvector for
         (healthy, disable or death) and IMaCh was corrected; but when we          memory allocation. But we also truncated to 8 characters (left
         introduced the exact date of death then we should have modified          truncation)
         the contribution of an exact death to the likelihood. This new          (Repository): No more line truncation errors.
         contribution is smaller and very dependent of the step unit  
         stepm. It is no more the probability to die between last interview  2003-06-14  Brouard Nicolas  <brouard@homebrou>
         and month of death but the probability to survive from last  
         interview up to one month before death multiplied by the          * imach.c (Repository): Add of a routine likelione (likelihood
         probability to die within a month. Thanks to Chris          only once) which prints on a text file
         Jackson for correcting this bug.  Former versions increased          (ilk) the contributions to the likelihood for each
         mortality artificially. The bad side is that we add another loop          individual/wave.
         which slows down the processing. The difference can be up to 10%  
         lower mortality.  2003-06-13  Brouard Nicolas  <brouard@homebrou>
   
 2002-05-30    <brouard@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.
         * imach.c (Module): Add correlation matrix of one-step  
         probabilities and covariance matrix  2003-06-17    <brouard@BROUARD>
   
           * timeval.h (Module): Added included file to make use of
           gettimeofday working on win32 with cygwin.

           * imach.c (Module): Insert of a warning if the delay between two
           waves is negative.
