     Short summary of the programme:
 /******************* ma3x *******************************/    
 double ***ma3x(long nrl, long nrh, long ncl, long nch, long nll, long nlh)    This program computes Healthy Life Expectancies from
 {    cross-longitudinal data. Cross-longitudinal data consist in: -1- a
   long i, j, nrow=nrh-nrl+1, ncol=nch-ncl+1, nlay=nlh-nll+1;    first survey ("cross") where individuals from different ages are
   double ***m;    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
   m=(double ***) malloc((size_t)((nrow+NR_END)*sizeof(double*)));    second wave of interviews ("longitudinal") which measure each change
   if (!m) nrerror("allocation failure 1 in matrix()");    (if any) in individual health status.  Health expectancies are
   m += NR_END;    computed from the time spent in each health state according to a
   m -= nrl;    model. More health states you consider, more time is necessary to reach the
     Maximum Likelihood of the parameters involved in the model.  The
   m[nrl]=(double **) malloc((size_t)((nrow*ncol+NR_END)*sizeof(double)));    simplest model is the multinomial logistic model where pij is the
   if (!m[nrl]) nrerror("allocation failure 2 in matrix()");    probability to be observed in state j at the second wave
   m[nrl] += NR_END;    conditional to be observed in state i at the first wave. Therefore
   m[nrl] -= ncl;    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
   for (i=nrl+1; i<=nrh; i++) m[i]=m[i-1]+ncol;    complex model than "constant and age", you should modify the program
     where the markup *Covariates have to be included here again* invites
   m[nrl][ncl]=(double *) malloc((size_t)((nrow*ncol*nlay+NR_END)*sizeof(double)));    you to do it.  More covariates you add, slower the
   if (!m[nrl][ncl]) nrerror("allocation failure 3 in matrix()");    convergence.
   m[nrl][ncl] += NR_END;  
   m[nrl][ncl] -= nll;    The advantage of this computer programme, compared to a simple
   for (j=ncl+1; j<=nch; j++)    multinomial logistic model, is clear when the delay between waves is not
     m[nrl][j]=m[nrl][j-1]+nlay;    identical for each individual. Also, if a individual missed an
      intermediate interview, the information is lost, but taken into
   for (i=nrl+1; i<=nrh; i++) {    account using an interpolation or extrapolation.  
     m[i][ncl]=m[i-1l][ncl]+ncol*nlay;  
     for (j=ncl+1; j<=nch; j++)    hPijx is the probability to be observed in state i at age x+h
       m[i][j]=m[i][j-1]+nlay;    conditional to the observed state i at age x. The delay 'h' can be
   }    split into an exact number (nh*stepm) of unobserved intermediate
   return m;    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
 /*************************free ma3x ************************/    and the contribution of each individual to the likelihood is simply
 void free_ma3x(double ***m, long nrl, long nrh, long ncl, long nch,long nll, long nlh)    hPijx.

   free((FREE_ARG)(m[nrl][ncl]+ nll-NR_END));    Also this programme outputs the covariance matrix of the parameters but also
   free((FREE_ARG)(m[nrl]+ncl-NR_END));    of the life expectancies. It also computes the period (stable) prevalence.
