  *** 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.

/*
   Interpolated Markov Chain

  Short summary of the programme:
  
  This program computes Healthy Life Expectancies from
  cross-longitudinal data. Cross-longitudinal data consist in: -1- a
  first survey ("cross") where individuals from different ages are
  interviewed on their health status or degree of disability (in the
  case of a health survey which is our main interest) -2- at least a
  second wave of interviews ("longitudinal") which measure each change
  (if any) in individual health status.  Health expectancies are
  computed from the time spent in each health state according to a
  model. More health states you consider, more time is necessary to reach the
  Maximum Likelihood of the parameters involved in the model.  The
  simplest model is the multinomial logistic model where pij is the
  probability to be observed in state j at the second wave
  conditional to be observed in state i at the first wave. Therefore
  the model is: log(pij/pii)= aij + bij*age+ cij*sex + etc , where
  'age' is age and 'sex' is a covariate. If you want to have a more
  complex model than "constant and age", you should modify the program
  where the markup *Covariates have to be included here again* invites
  you to do it.  More covariates you add, slower the
  convergence.

  The advantage of this computer programme, compared to a simple
  multinomial logistic model, is clear when the delay between waves is not
  identical for each individual. Also, if a individual missed an
  intermediate interview, the information is lost, but taken into
  account using an interpolation or extrapolation.  

  hPijx is the probability to be observed in state i at age x+h
  conditional to the observed state i at age x. The delay 'h' can be
  split into an exact number (nh*stepm) of unobserved intermediate
  states. This elementary transition (by month, quarter,
  semester or year) is modelled as a multinomial logistic.  The hPx
  matrix is simply the matrix product of nh*stepm elementary matrices
  and the contribution of each individual to the likelihood is simply
  hPijx.

  Also this programme outputs the covariance matrix of the parameters but also
  of the life expectancies. It also computes the period (stable) prevalence.

	     In version up to 0.92 likelihood was computed

	to consider that at each interview the state was recorded

	introduced the exact date of death then we should have modified
	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%
