Computing Analysis for an Independent Random Variable Sequence of Streamflows |
| |
| Abstract: | In this paper, goodness-of-fit of the Pearson Type Ⅲ probability density for describing a random variable of monthly streamflow is discussed. Both the method of moments and the maximum likelihood method are employed to estimate parameters of the Pearson type Ⅲ probability density function. Then their cumulative distributions are calculated respectively. The chi-square test is used to check the goodness-of-fit. Computation for a reservoir has showed the effectiveness of the computing analysis. |
