StatisticFormula.InverseFDistribution(Double, Int32, Int32) 方法

定义

返回 F 累积分布函数的反函数。Returns the inverse of the F cumulative distribution.

public:
 double InverseFDistribution(double probability, int firstDegreeOfFreedom, int secondDegreeOfFreedom);
public double InverseFDistribution (double probability, int firstDegreeOfFreedom, int secondDegreeOfFreedom);
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

Double

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.
