Abstract

In medical applications of survival analysis we are often interested in determining prognosis, and the adoption of statistical models in the establishment of a prognostic index has become common practice. The aim of this presentation is to examine the problem of re‐evaluation or the modification of any such index in the light of information subsequent to the initial assessment. Examples are given to highlight the approach.
