to the likelihood is the probability to die between last step unit time and current
|
|
step unit time, which is also the differences between probability to die before dh
|
|
and probability to die before dh-stepm .
|
|
In version up to 0.92 likelihood was computed
|
|
as if date of death was unknown. Death was treated as any other
|
|
health state: the date of the interview describes the actual state
|
|
and not the date of a change in health state. The former idea was
|
|
to consider that at each interview the state was recorded
|
|
(healthy, disable or death) and IMaCh was corrected; but when we
|
|
introduced the exact date of death then we should have modified
|
|
the contribution of an exact death to the likelihood. This new
|
|
contribution is smaller and very dependent of the step unit
|
|
stepm. It is no more the probability to die between last interview
|
|
and month of death but the probability to survive from last
|
|
interview up to one month before death multiplied by the
|
|
probability to die within a month. Thanks to Chris
|
|
Jackson for correcting this bug. Former versions increased
|
|
mortality artificially. The bad side is that we add another loop
|
|
which slows down the processing. The difference can be up to 10%
|
|
lower mortality.
