摘要
研究并解决了以下三个问题:关于Γ分布与Z分布间的关系,指出两个相互独立的Γ变量之商为Z变量;关于χ2分布与F分布间的关系,指出两个相互独立的χ2变量之商为F变量;关于上述两个问题的反问题.
This paper has mainly investigated following three problems. The first problem is about the relation between F distribution and Z distribution. The second problem is about the relation between x^2-distribution and F- distributio. The last problem is about the contrary of two above-mentioned problems.
