      Summary: Some errors to warnings only if date of death is unknown but status is death we could set to pi3
   This program computes Healthy Life Expectancies from

   (if any) in individual health status.  Health expectancies are    Revision 1.257  2017/03/29 16:53:30  brouard
   computed from the time spent in each health state according to a    Summary: Temp
   model. More health states you consider, more time is necessary to reach the  
   Maximum Likelihood of the parameters involved in the model.  The    Revision 1.256  2017/03/27 05:50:23  brouard
   simplest model is the multinomial logistic model where pij is the    Summary: Temporary

   'age' is age and 'sex' is a covariate. If you want to have a more

   The advantage of this computer programme, compared to a simple  
   multinomial logistic model, is clear when the delay between waves is not    Revision 1.252  2016/09/15 21:15:37  brouard
