-  This program computes Healthy Life Expectancies from cross-longitudinal 
-  data. Cross-longitudinal consist in a first survey ("cross") where 
-  individuals from different ages are interviewed on their health status
-  or degree of  disability. At least a second wave of interviews 
-  ("longitudinal") should  measure each new individual health status. 
-  Health expectancies are computed from the transistions observed between 
-  waves and are computed for each degree of severity of disability (number
-  of life states). More degrees 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 probabibility 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, less is the speed of the convergence.
-
-  The advantage that this computer programme claims, comes from that if the 
-  delay between waves is not identical for each individual, or if some 
-  individual missed an interview, the information is not rounded or 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.

+  Summary: 0.98q0, trying with directest, mnbrak fixed
+
+  We use directest instead of original Powell test; probably no
+  incidence on the results, but better justifications;
+  We fixed Numerical Recipes mnbrak routine which was wrong and gave
+  wrong results.

+
+  Lot of changes in order to output the results with some covariates
+  After the Edimburgh REVES conference 2014, it seems mandatory to

+  No more memory valgrind error but a lot has to be done in order to
+  continue the work of splitting the code into subroutines.
+  Also, decodemodel has been improved. Tricode is still not

+  (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

+  In the future we should be able to stop the program is only health

+  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 or State-specific
+  (if states aren't health statuses) 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.
+
+Back prevalence and projections:
+
+ - back_prevalence_limit(double *p, double **bprlim, double ageminpar,
+   double agemaxpar, double ftolpl, int *ncvyearp, double
+   dateprev1,double dateprev2, int firstpass, int lastpass, int
+   mobilavproj)
+
+    Computes the back prevalence limit for any combination of
+    covariate values k at any age between ageminpar and agemaxpar and
+    returns it in **bprlim. In the loops,
+
+   - **bprevalim(**bprlim, ***mobaverage, nlstate, *p, age, **oldm,
+       **savm, **dnewm, **doldm, **dsavm, ftolpl, ncvyearp, k);
+
+   - hBijx Back Probability to be in state i at age x-h being in j at x
+   Computes for any combination of covariates k and any age between bage and fage 
+   p3mat=ma3x(1,nlstate+ndeath,1, nlstate+ndeath, 0,nhstepm);
+ 			oldm=oldms;savm=savms;
+
+   - hbxij(p3mat,nhstepm,agedeb,hstepm,p,nlstate,stepm,oldm,savm, k);
+     Computes the transition matrix starting at age 'age' over
+     'nhstepm*hstepm*stepm' months (i.e. until
+     age (in years)  age+nhstepm*hstepm*stepm/12) by multiplying
+     nhstepm*hstepm matrices. 
+
+     Returns p3mat[i][j][h] after calling
+     p3mat[i][j][h]=matprod2(newm,
+     bmij(pmmij,cov,ncovmodel,x,nlstate,prevacurrent, dnewm, doldm,
+     dsavm,ij),\ 1,nlstate+ndeath,1,nlstate+ndeath,1,nlstate+ndeath,
+     oldm);
+
+Important routines
+
+- func (or funcone), computes logit (pij) distinguishing
+  o fixed variables (single or product dummies or quantitative);
+  o varying variables by:
+   (1) wave (single, product dummies, quantitative), 
+   (2) by age (can be month) age (done), age*age (done), age*Vn where Vn can be:
+       % fixed dummy (treated) or quantitative (not done because time-consuming);
+       % varying dummy (not done) or quantitative (not done);
+- Tricode which tests the modality of dummy variables (in order to warn with wrong or empty modalities)
+  and returns the number of efficient covariates cptcoveff and modalities nbcode[Tvar[k]][1]= 0 and nbcode[Tvar[k]][2]= 1 usually.
+- printinghtml which outputs results like life expectancy in and from a state for a combination of modalities of dummy variables
+  o There are 2*cptcoveff combinations of (0,1) for cptcoveff variables. Outputting only combinations with people, éliminating 1 1 if
+    race White (0 0), Black vs White (1 0), Hispanic (0 1) and 1 1 being meaningless.
