   m[nrl]=(double **) malloc((size_t)((nrow*ncol+NR_END)*sizeof(double)));    This program computes Healthy Life Expectancies from
   if (!m[nrl]) nrerror("allocation failure 2 in matrix()");    cross-longitudinal data. Cross-longitudinal data consist in: -1- a
   m[nrl] += NR_END;    first survey ("cross") where individuals from different ages are
   m[nrl] -= ncl;    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
   for (i=nrl+1; i<=nrh; i++) m[i]=m[i-1]+ncol;    second wave of interviews ("longitudinal") which measure each change
     (if any) in individual health status.  Health expectancies are
   m[nrl][ncl]=(double *) malloc((size_t)((nrow*ncol*nlay+NR_END)*sizeof(double)));    computed from the time spent in each health state according to a
   if (!m[nrl][ncl]) nrerror("allocation failure 3 in matrix()");    model. More health states you consider, more time is necessary to reach the
   m[nrl][ncl] += NR_END;    Maximum Likelihood of the parameters involved in the model.  The
   m[nrl][ncl] -= nll;    simplest model is the multinomial logistic model where pij is the
   for (j=ncl+1; j<=nch; j++)    probability to be observed in state j at the second wave
     m[nrl][j]=m[nrl][j-1]+nlay;    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
   for (i=nrl+1; i<=nrh; i++) {    'age' is age and 'sex' is a covariate. If you want to have a more
     m[i][ncl]=m[i-1l][ncl]+ncol*nlay;    complex model than "constant and age", you should modify the program
     for (j=ncl+1; j<=nch; j++)    where the markup *Covariates have to be included here again* invites
       m[i][j]=m[i][j-1]+nlay;    you to do it.  More covariates you add, slower the
