This article addresses a connection between the Bradley and Terry (1952A) model and Cox (1972) proportional hazards model. We show that the partial likelihood of random variables that satisfy the stratified proportional hazards assumption of Cox (1972) coincides with the likelihood given by the Bradley-Terry (BT) model for rank order events. Such a connection not only allows many available soft...

The case-crossover method is an efficient study design for evaluating associations between transient exposures and the onset of acute events. In one common implementation of this design, odds ratios are estimated using conditional logistic or stratified Cox proportional hazards models, with data stratified on each individual event. In environmental epidemiology, where aggregate time-series data...

We describe a full maximum-likelihood fitting method of the popular single-factor Vasicek and Cox–Ingersoll–Ross models and carry this out for term-structure data from the UK and US. This method contrasts with the usual practice of performing a day-by-day fit. We also compare the results with some more crude econometric analyses on the same data sets. © 2000 Elsevier Science B.V.
