Compute the value of CDF over Wilcoxon Signedrank Distribution in R Programming – psignrank() Function
  • Last Updated : 25 Jun, 2020

psignrank() function in R Language is used to compute the value of Cumulative Density Function(CDF) over Wilcoxon Signedrank Statistic Distribution for a sequence of Numeric values.

Syntax: psignrank(x, n)

Parameters:
x: Numeric Vector
n: Sample Size

Example 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

Output:



 [1] 0.0009765625 0.0019531250 0.0029296875 0.0048828125 0.0068359375
 [6] 0.0097656250 0.0136718750 0.0185546875 0.0244140625 0.0322265625
[11] 0.0419921875 0.0527343750 0.0654296875 0.0800781250 0.0966796875
[16] 0.1162109375 0.1376953125 0.1611328125 0.1875000000 0.2158203125
[21] 0.2460937500

Example 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)
