     This program computes Healthy Life Expectancies from
 /*************** linmin ************************/    cross-longitudinal data. Cross-longitudinal data consist in: -1- a
     first survey ("cross") where individuals from different ages are
 int ncom;    interviewed on their health status or degree of disability (in the
 double *pcom,*xicom;    case of a health survey which is our main interest) -2- at least a
 double (*nrfunc)(double []);    second wave of interviews ("longitudinal") which measure each change
      (if any) in individual health status.  Health expectancies are
 void linmin(double p[], double xi[], int n, double *fret,double (*func)(double []))    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
   double brent(double ax, double bx, double cx,    Maximum Likelihood of the parameters involved in the model.  The
                double (*f)(double), double tol, double *xmin);    simplest model is the multinomial logistic model where pij is the
   double f1dim(double x);    probability to be observed in state j at the second wave
   void mnbrak(double *ax, double *bx, double *cx, double *fa, double *fb,    conditional to be observed in state i at the first wave. Therefore
               double *fc, double (*func)(double));    the model is: log(pij/pii)= aij + bij*age+ cij*sex + etc , where
   int j;    'age' is age and 'sex' is a covariate. If you want to have a more
   double xx,xmin,bx,ax;    complex model than "constant and age", you should modify the program
   double fx,fb,fa;    where the markup *Covariates have to be included here again* invites
      you to do it.  More covariates you add, slower the
   ncom=n;    convergence.
   pcom=vector(1,n);  
   xicom=vector(1,n);    The advantage of this computer programme, compared to a simple
   nrfunc=func;    multinomial logistic model, is clear when the delay between waves is not
   for (j=1;j<=n;j++) {    identical for each individual. Also, if a individual missed an
     pcom[j]=p[j];    intermediate interview, the information is lost, but taken into
     xicom[j]=xi[j];    account using an interpolation or extrapolation.  
   }  
   ax=0.0;    hPijx is the probability to be observed in state i at age x+h
   xx=1.0;    conditional to the observed state i at age x. The delay 'h' can be
   mnbrak(&ax,&xx,&bx,&fa,&fx,&fb,f1dim);    split into an exact number (nh*stepm) of unobserved intermediate
   *fret=brent(ax,xx,bx,f1dim,TOL,&xmin);    states. This elementary transition (by month, quarter,
 #ifdef DEBUG    semester or year) is modelled as a multinomial logistic.  The hPx
   printf("retour brent fret=%.12e xmin=%.12e\n",*fret,xmin);    matrix is simply the matrix product of nh*stepm elementary matrices
 #endif    and the contribution of each individual to the likelihood is simply
   for (j=1;j<=n;j++) {    hPijx.
     xi[j] *= xmin;  
     p[j] += xi[j];    Also this programme outputs the covariance matrix of the parameters but also
