| Abstract: | Firstly, four point estimators of the parameter are given from uniform distribution ; Secondly, moment estimation and maxi- mum likelihood estimation are introduced. Through calculating their expectation and variance, four kinds of estimator unbiasedness, congruence and validity are judged; At last, interval estimation about parameter is given. |
