This package implements a fast product-limit algorithm to calculate the non-parametric maximum likelihood estimator for LTIC data. This also includes simulations and plots from the paper "A fast and stable NPMLE estimator for left-truncated and interval-censored data".

The above paper applies these methods to the Massachusetts Health Care Panel dataset. This data is available from the supporting information from Pan and Chappell (2002), here.
Some changes need to be made to that data to make it make sense - there are some
lines overlapping and lack of spaces between certain columns. Aside from the new
lines changes, the other changes are shown in tests/mhcps.R.
