| Abstract: | A method of measuring the heterogeneity of policyholders has been studies based on the mixed Poisson distribution which be used prevalently to describe the numbers of claims in insurance. The coefficient of the heterogeneity of policyholders be definited and estimated by the moments mothed. Moreover, some examples have been investigated in this paper. |
