Dear All I am pleased to announce that there will be another talk to theRSSNI Local Group on Tuesday, December 3rd, at 3pm (note the change of date and time) in the Peter Froggatt Centre (Room 2.011) in The Queen's University of Belfast. The Peter Froggatt Centre isoff the main quadrangle. Another Look at Prediction and Explained Variation in Event History Analysis Professor Robin Henderson, University of Newcastle, UK. This talk revisits the related issues of prediction and explained variation for survival and more general event history data. There is no shortage of proposed measures of prognostic value for statistical models, especially proportional hazards, but none have been uniformly accepted and those in use in major computer packages may not be the most statistically meaningful. In this talk I review the issues and describe and illustrate use of a rank-based measure, developed in collaboration with Janez Stare and Maja Pohar, which is applicable and interpretable in discrete or continuous time, with tied data or otherwise, with time-varying, time-fixed or dynamic covariates, with time-varying or time-constant effects, with single or multiple event times, with parametric or semi-parametric models, and under general independent censoring/observation. Recall that ALL are welcome to RSSNI meetings. Again please note that this meeting is being held on a Tuesday, not a Wednesday, and at 3pm, not 4pm and in the Peter Froggatt Centre off the main Quad. Best wishes Gilbert MacKenzie Hon.
