-   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 or quarter trimester,
-  semester or year) is model 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 prevalence limits.

+  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.

+/*
+   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.
