John Kolassa Department of Statistics Rutgers University Location: Carslaw 273 Time: 2pm Friday, March 23, 2012 Title: Infinite Parameter Estimates in Polytomous Regression Abstract: We discuss a variety of methods for inference for polytomous regression models,when model parameters are estimated at infinity. The suggested result is a special case of the method of Kolassa (1997). Competing techniques, including that of Firth (1993), are described. As time permits, connections to proportional hazards regression are discussed. Join work with Juan Zhang.
