R语言 计算Wilcoxon Signedrank分布的CDF值 – psignrank()函数

R语言中的 psignrank() 函数用于计算一串数值的Wilcoxon Signedrank统计分布的累积密度函数（CDF）值。

语法： psignrank(x, n)

参数：

x： 数字向量

n： 样本大小

例1 :

# R Program to compute the value of
# CDF over Wilcoxon Signedrank Distribution
  
# Creating a sequence of x-values
x <- seq(0, 20, by = 1)
  
# Calling psignrank() Function
y <- psignrank(x, n = 10)
y

输出

例2 :

# R Program to compute the value of
# CDF over Wilcoxon Signedrank Distribution
  
# Creating a sequence of x-values
x <- seq(1, 100, by = 1)
  
# Calling psignrank() Function
y <- psignrank(x, n = 15)
  
# Plot a graph
plot(y)
