     Revision 1.321  2022/07/22 12:04:24  brouard
     Summary: r28
   
   Short summary of the programme:    *  imach.c (Module): Output of Wald test in the htm file and not only in the log.
     
   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    Revision 1.320  2022/06/02 05:10:11  brouard
   multinomial logistic model, is clear when the delay between waves is not    *** empty log message ***
   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    Revision 1.319  2022/06/02 04:45:11  brouard

   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    Revision 1.318  2022/05/24 08:10:59  brouard

     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
     optimal. nbcode should be improved. Documentation has been added in
     the source code.

     *** 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.

     * 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

     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 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, nres);
        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.

                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
