Downloadable (with restrictions)! Multivariate failure time data arise when data consist of clusters in which the failure times may be dependent. A popular approach to such data is the marginal proportional hazards model with estimation under the working independence assumption. ... In this paper, ... Christian Bressen Pipper;

The Likelihood equation for a multi-cell acceleration model starts by computing the Likelihood functions for each cell, as was described earlier. Each cell will have unknown life distribution parameters that, in general, are different.

Additional file 2. Example of log-likelihood function [equation (1)] for estimating population frequencies from pool frequencies. This example shows the likelihood surface for the three possible combinations of x’s that yield a total of 4 pools with detected element presence [i.e. for (x1, x2) equal to (0, 4), (1,
