Abstract
The influence function and its role in regression analysis is discussed. Also review various sample versions of the influence function which provide the basis and justification for various techniques used for the detection of influential cases. Different methodologies for assessing the influence of individual or group of cases on regression analysis have also been surveyed. However, the discussion is confined to those aspects of analysis that can be summarized by sample influence function.
