                     17: 
                     18:        * imach.c (Module): In version up to 0.92 likelihood was computed
                     19:        as if date of death was unknown. Death was treated as any other
                     20:        health state: the date of the interview describes the actual state
                     21:        and not the date of a change in health state. The former idea was
                     22:        to consider that at each interview the state was recorded
                     23:        (healthy, disable or death) and IMaCh was corrected; but when we
                     24:        introduced the exact date of death then we should have modified
                     25:        the contribution of an exact death to the likelihood. This new
                     26:        contribution is smaller and very dependent of the step unit
                     27:        stepm. It is no more the probability to die between last interview
                     28:        and month of death but the probability to survive from last
                     29:        interview up to one month before death multiplied by the
                     30:        probability to die within a month. Thanks to Chris
                     31:        Jackson for correcting this bug.  Former versions increased
                     32:        mortality artificially. The bad side is that we add another loop
                     33:        which slows down the processing. The difference can be up to 10%
                     34:        lower mortality.
