The statistical analysis of a collection of data is usually based on a specified model, a mathematical formula describing the behavior of the data up to a few unknown parameters which are to be estimated from the data. The specification of a model often involves making assumptions that may have little prior support. In such situations it becomes necessary to understand if important results of an analysis are strongly dependent on the validity of assumptions underlying the model. The purpose of this paper is to provide a method for assessing the influence of minor model perturbations on the results of an analysis.
