Cross-longitudinal data consist in: -1- a + first survey ("cross") where individuals from different ages are + interviewed on their health status or degree of disability (in the + case of a health survey which is our main interest) -2- at least a + second wave of interviews ("longitudinal") which measure each change + (if any) in individual health status.

Also this programme outputs the covariance matrix of the parameters but also of the life expectancies.
