摘要
在应用t,X^2和F分布作检验时,为了计算检验的功效,必然要引出相应的非中心t,X^2和F分布,具体公式参看.通常,人们最关心的问题是,对于某种检验方法,当犯第一类错误的概率α固定以后,非中心分布非中心参数λ应取什么样值。
In this paper, some problems in iterative computation for non-centrality parameters ofnoncentral t, X^2 and F distributions are discussed. Based on a large amount of computationalsimulation a selective approach for the initial formula is presented, the practical effectiveness oftwo iterative formulas is analyzed, and a few better iterative intervals are suggested. Thus com-putational efficiency increases greatly.
