✦ Synopsis


A Monte Carlo procedure is proposed for testing homogeneity of variances in linear models. The method is applicable to a variety of common experimental designs. It is valid when errors are independently normally distributed. Under nonnormality the test is expected to behave robust in a similar fashion as LEVENE'S test. Three examples are given to demonstrate the method.

The problem of testing for a centre e!ect in multi-centre studies following a proportional hazards regression analysis is considered. Two approaches to the problem can be used. One "ts a proportional hazards model with a "xed covariate included for each centre (except one). The need for a centre spe

A simple method for incorporating bond-length constraints in Monte Carlo simulations of cyclic and linear molecules is described. As an example, the conformational behavior of five even-numbered cyclic alkanes is studied using Monte Carlo simulation and the MM2 force field.
