摘要
本文用数学归纳法证明了x^2分布及其性质、统计量((n-1)s^2)/σ~2的分布,使不具备线性代数和较多微积分知识的读者也易于理解。
This paper proves X2 distribution and its nature, and the statistical quantity of the distribution of by mathematical induction, which is easilycom-prehensible to teaders knowing little about infinitesimal calculus or ignorant of linear algebra.
