Reformulations of the semi‐proportional hazards model are outlined making estimation and testing of stratum‐covariate interaction effects easily accessible within the framework of the stratified Cox proportional hazards model. The method is illustrated by a practical analysis of variables influencing bronchial responsiveness with data from the Hordaland study of obstructive lung disease.
