|Title||When to use ltable versus sts list|
|Author||William Sribney, StataCorp|
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.
