地质变量概率分布拟合优度检验之新探

Probe into the Goodness-of-fit of probability Distributions of Geological Variables

提出当地质变量可能同时符合几种概率分布，并对其概率分布作检验时，应重视检验样本对何种分布符合得好；还介绍了用ω￣２检验法解决此问题的途径，ω￣２检验法与Ｗ检验法、Ｄ检验法的关系及稳健估算样本参数的方法。

The geological variables presented in this paper may be fit several probability distributions.The samples tested would be consideredto fit which distribution when testing the probability distributions of geological variables.The author introduced the way solving thisproblem with ω￣2 test,that is,the reliable method to estimate the parameters of the samples and the relationship among ω￣2 test,Wtestand D test.
