If are ''k'' independent, normally distributed random variables with means and variances , then the statistic : is distributed according to the noncentral chi distribution. The noncentral chi distribution has two parameters: which specifies the number of degrees of freedom (i.e. the number of ), and which is related to the mean of the random variables by: : ==Properties== 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「noncentral chi distribution」の詳細全文を読む スポンサード リンク
