     Short summary of the programme:

 int **s; /* Status */    This program computes Healthy Life Expectancies from
 double *agedc, **covar, idx;    cross-longitudinal data. Cross-longitudinal data consist in: -1- a

     interviewed on their health status or degree of disability (in the
 double ftol=FTOL; /* Tolerance for computing Max Likelihood */    case of a health survey which is our main interest) -2- at least a
 double ftolhess; /* Tolerance for computing hessian */    second wave of interviews ("longitudinal") which measure each change
     (if any) in individual health status.  Health expectancies are
     computed from the time spent in each health state according to a
 static  int split( char *path, char *dirc, char *name )    model. More health states you consider, more time is necessary to reach the
 {    Maximum Likelihood of the parameters involved in the model.  The
    char *s;                             /* pointer */    simplest model is the multinomial logistic model where pij is the
    int  l1, l2;                         /* length counters */    probability to be observed in state j at the second wave
     conditional to be observed in state i at the first wave. Therefore
    l1 = strlen( path );                 /* length of path */    the model is: log(pij/pii)= aij + bij*age+ cij*sex + etc , where
    if ( l1 == 0 ) return( GLOCK_ERROR_NOPATH );    'age' is age and 'sex' is a covariate. If you want to have a more
    s = strrchr( path, '\\' );           /* find last / */    complex model than "constant and age", you should modify the program
    if ( s == NULL ) {                   /* no directory, so use current */    where the markup *Covariates have to be included here again* invites
