   m += NR_END;    computed from the time spent in each health state according to a

   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] -= 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
