在 R 编程中计算 CDF 在学生化范围分布上的值 – ptukey()函数

R 语言中的ptukey()函数用于计算一系列数值在学生化范围内的累积分布函数(CDF) 的值。

Syntax: ptukey(x, nmeans, df)

Parameters:
x: Numeric Vector
nmeans: Number of means
df: Degree of Freedom

示例 1：

# R Program to compute the value of
# CDF for Studentized Range
  
# Creating a sequence of Numeric values
x <- seq(1, 10, by = 1)
  
# Calling ptukey() Function
y <- ptukey(x, nmeans = 7, df = 5)
y

输出：

[1] 0.01416051 0.22099429 0.54676395 0.76823006 0.88284988 0.93871676
 [7] 0.96637587 0.98063547 0.98833593 0.99268670

示例 2：

# R Program to compute the value of
# CDF for Studentized Range
  
# Creating a sequence of Numeric values
x <- seq(1, 10, by = 0.2)
  
# Calling ptukey() Function
y <- ptukey(x, nmeans = 8, df = 7)
  
# Plot a graph
plot(y)

输出：
