ISDM: Estimate the NPMLE of censored data using the ISDM method...

In Icens: NPMLE for Censored and Truncated Data

Description

ISDM is a method for estimating the NPMLE of censored data.

Usage

ISDM(A, pvec, maxiter=500, tol=1e-07, tolbis=1e-08, verbose=FALSE)

Arguments

A	The m by n incidence, or clique, matrix. Or the n by 2 matrix containing the event intervals.
pvec	An initial estimate of the probability vector; not required.
maxiter	Maximum number of iterations to be made.
tol	The tolerance used to determine convergence.
tolbis	A second tolerance used for the steps.
verbose	Boolean, should verbose output be printed.

Details

Lots of complicated stuff should go here.

Value

A list containing:

pf	The estimated NPMLE of the probability vector.
numiter	The number of iterations performed.
