    2: 
    3: 	* imach.c (Module): sump fixed, loop imx fixed, and simplifications.
    4: 	(Module): If the status is missing at the last wave but we know
    5: 	that the person is alive, then we can code his/her status as -2
    6: 	(instead of missing=-1 in earlier versions) and his/her
    7: 	contributions to the likelihood is 1 - Prob of dying from last
    8: 	health status (= 1-p13= p11+p12 in the easiest case of somebody in
    9: 	the healthy state at last known wave). Version is 0.98 
   10: 
   11: 2004-05-20  Brouard Nicolas  <brouard@localhost>
   12: 
   13: 	* imach.c (Repository): 
   14: 	Agnes added a direct estimation of mortality (without the need of
   15: 	computing period prevalence and differential mortality). Thus here
   16: 	is version 0.97a which has been distributed to some people at
   17: 	REVES 16 in Brugge using an Inno setup.exe for PCs. Estimates of
   18: 	mortality using covariates is not done today. Estimating direct
   19: 	mortality is a very different process because it doesn't need
   20: 	interpolation because it is easy to get the lx from the force of
   21: 	the mortality mux in the simplest case as for a Gompertz (log mux
   22: 	= a + b*x . But we have been able to incorporate the new code
   23: 	within former imach program (0.96d) without deteriorating too much
   24: 	the understanding of the program. 
   25: 
   26: 2003-06-25    <brouard@BROUARD>
   27: 
   28: 	* imach.c (Module): On windows (cygwin) function asctime_r doesn't
   29: 	exist so I changed back to asctime which exists.
   30: 	(Module): Version 0.96b
   31: 
   32: 2003-06-24    <brouard@BROUARD>
   33: 
   34: 	* imach.c (Module): Some bugs corrected for windows. Also, when
   35: 	mle=-1 a template is output in file "or"mypar.txt with the design
   36: 	of the covariance matrix to be input.
   37: 
   38: 2003-06-25  Brouard Nicolas  <brouard@homebrou>
   39: 
   40: 	* imach.c (Repository): Duplicated warning errors corrected.
   41: 	(Repository): Elapsed time after each iteration is now output. It
   42: 	helps to forecast when convergence will be reached. Elapsed time
   43: 	is stamped in powell.  We created a new html file for the graphs
   44: 	concerning matrix of covariance. It has extension -cov.htm.
   45: 
   46: 2003-06-23  Brouard Nicolas  <brouard@homebrou>
   47: 
   48: 	* 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.
   49: 
   50: 2003-06-18  Brouard Nicolas  <brouard@homebrou>
   51: 
   52: 	* imach.c (Repository): Suppress abusive calls to append to file html (solution was to put fichtm as a global variable. Version 0.96
   53: 
   54: 2003-06-17  Brouard Nicolas  <brouard@homebrou>
   55: 
   56: 
   57: 	* imach.c (Repository): Check when date of death was earlier that
   58: 	current date of interview. It may happen when the death was just
   59: 	prior to the death. In this case, dh was negative and likelihood
   60: 	was wrong (infinity). We still send an "Error" but patch by
   61: 	assuming that the date of death was just one stepm after the
   62: 	interview.
   63: 	(Repository): Because some people have very long ID (first column)
   64: 	we changed int to long in num[] and we added a new lvector for
   65: 	memory allocation. But we also truncated to 8 characters (left
   66: 	truncation)
   67: 
   68: 	(Repository): No more line truncation errors.
   69: 
   70: 2003-06-14  Brouard Nicolas  <brouard@homebrou>
   71: 
   72: 	* imach.c (Repository): Add of a routine likelione (likelihood
   73: 	only once) which prints on a text file
   74: 	(ilk) the contributions to the likelihood for each
   75: 	individual/wave.
   76: 
   77: 2003-06-13  Brouard Nicolas  <brouard@homebrou>
   78: 	* imach.c (Repository): Replace "freqsummary" at a correct
   79: 	place. It differs from routine "prevalence" which may be called
   80: 	many times. Probs is memory consuming and must be used with
   81: 	parcimony.
   82: 
   83: 2003-06-17    <brouard@BROUARD>
   84: 
   85: 	* timeval.h (Module): Added included file to make use of
   86: 	gettimeofday working on win32 with cygwin.
   87: 
   88: 2003-05-16  Brouard Nicolas  <brouard@brouard>
   89: 	* imach.c (Module): Insert of a warning if the delay between two
   90: 	waves is negative.
   91: 
   92: 	* imach.c (Module): 
   93: 
   94: 2003-05-03    <brouard@BROUARD>
   95: 
   96: 	* imach.c: Some cleaning
   97: 
   98: 2003-03-28    <brouard@BROUARD>
   99: 	* imach.c (Module): In version up to 0.92 likelihood was computed
  100: 	as if date of death was unknown. Death was treated as any other
  101: 	health state: the date of the interview describes the actual state
  102: 	and not the date of a change in health state. The former idea was
  103: 	to consider that at each interview the state was recorded
  104: 	(healthy, disable or death) and IMaCh was corrected; but when we
  105: 	introduced the exact date of death then we should have modified
  106: 	the contribution of an exact death to the likelihood. This new
  107: 	contribution is smaller and very dependent of the step unit
  108: 	stepm. It is no more the probability to die between last interview
  109: 	and month of death but the probability to survive from last
  110: 	interview up to one month before death multiplied by the
  111: 	probability to die within a month. Thanks to Chris
  112: 	Jackson for correcting this bug.  Former versions increased
  113: 	mortality artificially. The bad side is that we add another loop
  114: 
  115: 
  116: 	which slows down the processing. The difference can be up to 10%
  117: 
  118: 
  119: 	lower mortality.

  137: 	* imach.c (Module): Add correlation matrix of one-step

  140: 	probabilities and covariance matrix
