                      3:   This program computes Healthy Life Expectancies from cross-longitudinal 
                      4:   data. Cross-longitudinal consist in a first survey ("cross") where 
                      5:   individuals from different ages are interviewed on their health status
                      6:   or degree of  disability. At least a second wave of interviews 
                      7:   ("longitudinal") should  measure each new individual health status. 
                      8:   Health expectancies are computed from the transistions observed between 
                      9:   waves and are computed for each degree of severity of disability (number
                     10:   of life states). More degrees you consider, more time is necessary to
                     11:   reach the Maximum Likelihood of the parameters involved in the model.
                     12:   The simplest model is the multinomial logistic model where pij is
                     13:   the probabibility to be observed in state j at the second wave conditional
                     14:   to be observed in state i at the first wave. Therefore the model is:
                     15:   log(pij/pii)= aij + bij*age+ cij*sex + etc , where 'age' is age and 'sex' 
                     16:   is a covariate. If you want to have a more complex model than "constant and
                     17:   age", you should modify the program where the markup 
                     18:     *Covariates have to be included here again* invites you to do it.
                     19:   More covariates you add, less is the speed of the convergence.
                     20: 
                     21:   The advantage that this computer programme claims, comes from that if the 
                     22:   delay between waves is not identical for each individual, or if some 
                     23:   individual missed an interview, the information is not rounded or lost, but
                     24:   taken into account using an interpolation or extrapolation.
                     25:   hPijx is the probability to be
                     26:   observed in state i at age x+h conditional to the observed state i at age 
                     27:   x. The delay 'h' can be split into an exact number (nh*stepm) of 
                     28:   unobserved intermediate  states. This elementary transition (by month or 
                     29:   quarter trimester, semester or year) is model as a multinomial logistic. 
                     30:   The hPx matrix is simply the matrix product of nh*stepm elementary matrices
                     31:   and the contribution of each individual to the likelihood is simply hPijx.
                     32: 
                     33:   Also this programme outputs the covariance matrix of the parameters but also
                     34:   of the life expectancies. It also computes the prevalence limits.
