Analyzing Infrequent Events: Once You Find Them Your Troubles Begin.

Abstract

A theoretical/methodological analysis of the study of infrequent or low base rate events and behaviors is presented. Problems of interpretation caused by aggregation across arbitrary time limits imposed by the necessity to obtain variance in dependent measures, aggregation across heterogeneous samples drawn from unspecified populations, studies of rates of occurrences per group, studies of surrogates with less extreme base rates, and studies of post hoc groups defines after the occurrences of the event are all discussed. The problems with each attempt to circumvent extremes of base rates were considered. Available alternatives were presented and discussed. (Author)
