member this.InverseFDistribution : double * int * int -> double
Public Function InverseFDistribution (probability As Double, firstDegreeOfFreedom As Integer, secondDegreeOfFreedom As Integer) As Double
参数
- probability
- Double
alpha 值,其表示假设被否定的概率。The alpha value, which is the probability that the hypothesis is rejected. 允许的范围是 0 到 1。The allowable range is 0-1.
- firstDegreeOfFreedom
- Int32
第一个自由度。First degree of freedom.
- secondDegreeOfFreedom
- Int32
第二个自由度。Second degree of freedom.
返回
F 分布反函数中的 double 值。A double value from the inverse F distribution function.
例外
状况:由于受限,无法使用指定参数值继续计算。Condition: Cannot continue calculation using specified parameter values because of limitation.
注解
此方法返回给定 F 分布概率的 F 值。This method returns the F value for the given F distribution probability.
F 分布可以用于比较两个数据集中的可变性程度的 F 检验。The F distribution can be used in an F-test that compares the degree of variability in two data sets.
此方法可能会返回一个异常,具体取决于参数值。This method may return an exception depending on the parameter values.
