Note on the Frequency Curves of Basic Pure Premiums

The question of a proper method of computing basic pure premiums in workmen's compensation insurance is of prime importance to all casualty statisticians and actuaries and can in no way be said to be finally solved. In the last number of this publication I gave a brief outline of a method for collecting data to be used in the calculation of pure premiums. This method, which was based on the theory of dispersion or stability of statistical series, was an attempt to determine the occupational hazard of the individual employee rather than the hazard according to industries.
