NPMLE (using GP), NPMLE (using EM) and INE for left-truncated and interval-censored data. INE for left-truncated and right-censored data. A NEW Splus program for INE for left-truncated and right-censored data; it also contains a function to use the nonparametric bootstrap to calculate point-wise confidence intervals of the survival probabilities.
