| Abstract: | In the non|life insurance, the distribution of the number of claim can be assumed as the Possion distribution P(λ). When the risk is inhomogeneous, the distribution of λ is called as mixed distribution. In this paper, parameter estimation and test will be considered when three|parameter Γ distribution is taken as mixed distribution. |
| Keywords: | non|life insurance the number of claim Possion distribution three|parameter Γdistribution estimation test |
