A Method of Assembling and Analyzing the Data Reported Under theUnit Statistical Plan

The essential features of the New York Unit Statistical Plan, as well as the events leading to its adoption, have been stated comprehensively in Mr. Graham's paper* dealing with the method used by a carrier in the preparation of the data to be reported under the provisions of the Plan. The Plan was designed with the following objects in view: (a) to determine to what extent the manual rules are observed and thus to correct improper underwriting practices, (b) to use the same experience in the merit rating of risks and in the determination of classification pure premiums and (c) to ascertain the degree of difference between small and large risks. In this paper an attempt is made to describe the methods of assembling, analyzing and tabulating individual risk experience by a central organization in its efforts to fulfill the aims of the Unit Statistical Plan.
