   This program computes Healthy Life Expectancies from cross-longitudinal    $Log$

   Health expectancies are computed from the transistions observed between    Summary: temporary not working
   waves and are computed for each degree of severity of disability (number  
   of life states). More degrees you consider, more time is necessary to    Revision 1.213  2015/12/11 18:22:17  brouard

   the probabibility to be observed in state j at the second wave conditional    Revision 1.212  2015/11/21 12:47:24  brouard
   to be observed in state i at the first wave. Therefore the model is:    Summary: minor typo

   is a covariate. If you want to have a more complex model than "constant and    Revision 1.211  2015/11/21 12:41:11  brouard
