The Estimation of Response-Time Distributions. II. Multi-Stimulus Distributions

Abstract

This is the 2d of 3 papers dealing with analyses of response-time data. The author here deals with response-time studies in which the response can result from any 2 or more stimuli. He identifies the "accidental death" model in which the stimuli act independently and the "natural death" model in which the stimuli may or may not act independently. Both models are discussed in detail with computational procedures for estimation and testing of hypotheses illustrated in two examples. A lengthy table is included which greatly facilitates the somewhat laborious iterative processes required to obtain sample estimates. Consideration is given to the case of truncated samples, methods for which have been proposed by other authors.
