โฆ Synopsis
Minimum likelihood allocation (MLA) is a new method for sequentially assigning subjects to treatment groups in a clinical trial. Its aim is to balance the trial, that is, to prevent various treatment groups from containing subjects who have much better or much worse prognoses than the average. The overall strategy of MLA is described, an illustrative example is provided, and the availability of the required computer program is announced.

Clinical scientists are becoming increasingly aware of the need to monitor clinical trials in progress, and to validate their procedure by the use of a formal sequential design. An interactive program, written in FORTRAN 77 and called "PEST: Planning and Evaluation of Sequential Tests," is introduce
In some clinical trials where the experimental treatment is found to beeffective in increasing survival, an important question is how long should the patient remain under treatment. Although the trial may not be designed to specifically answer this question, comparisons of the hazard curves among th
