What is the difference between sts list and ltable?
||When to use ltable versus sts list
William Sribney, StataCorp
The major difference between
sts list and
ltable is the
actuarial adjustment. You should use ltable if you want the
actuarial adjustment; otherwise use sts list.
Another difference is that ltable aggregrates the data, whereas
sts does not. This means that the accuracy of ltable can be
less than sts.
For example, at(0 12:60) with sts list gives accurate numbers;
it’s just as if you read off the Kaplan–Meier curve at these
values. There is no aggregation.
interval(12) with ltable, however, aggregates the data into
these intervals. There can be loss of accuracy.
