 }    (if any) in individual health status.  Health expectancies are
     computed from the time spent in each health state according to a
 /******************* imatrix *******************************/    model. More health states you consider, more time is necessary to reach the
 int **imatrix(long nrl, long nrh, long ncl, long nch)    Maximum Likelihood of the parameters involved in the model.  The
      /* allocate a int matrix with subscript range m[nrl..nrh][ncl..nch] */    simplest model is the multinomial logistic model where pij is the
 {    probability to be observed in state j at the second wave
   long i, nrow=nrh-nrl+1,ncol=nch-ncl+1;    conditional to be observed in state i at the first wave. Therefore
   int **m;    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
   /* allocate pointers to rows */    complex model than "constant and age", you should modify the program
   m=(int **) malloc((size_t)((nrow+NR_END)*sizeof(int*)));    where the markup *Covariates have to be included here again* invites
   if (!m) nrerror("allocation failure 1 in matrix()");    you to do it.  More covariates you add, slower the
   m += NR_END;    convergence.
   m -= nrl;  
      The advantage of this computer programme, compared to a simple
      multinomial logistic model, is clear when the delay between waves is not
   /* allocate rows and set pointers to them */    identical for each individual. Also, if a individual missed an
   m[nrl]=(int *) malloc((size_t)((nrow*ncol+NR_END)*sizeof(int)));    intermediate interview, the information is lost, but taken into
   if (!m[nrl]) nrerror("allocation failure 2 in matrix()");    account using an interpolation or extrapolation.  
   m[nrl] += NR_END;  
   m[nrl] -= ncl;    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
   for(i=nrl+1;i<=nrh;i++) m[i]=m[i-1]+ncol;    split into an exact number (nh*stepm) of unobserved intermediate
      states. This elementary transition (by month, quarter,
   /* return pointer to array of pointers to rows */    semester or year) is modelled as a multinomial logistic.  The hPx
   return m;    matrix is simply the matrix product of nh*stepm elementary matrices
 }    and the contribution of each individual to the likelihood is simply
     hPijx.
