Compute the value of PDF over Wilcoxon Rank Sum Distribution in R Programming – dwilcox() Function

dwilcox() function in R Language is used to compute the value of Probability Density Function(PDF) for Wilcoxonrank Sum Statistic Distribution over a sequence of Numeric Values.

Syntax: dwilcox(x, m, n)

Parameters:
x: Numeric Vector
m: Larger sample size
n: Smaller sample size

Example 1:

# R Program to compute the value of
# PDF over Wilcoxonrank Sum Distribution

# Creating a sequence of x-values
x <- seq(1, 10, by = 1)

# Calling dwilcox() Function
y <- dwilcox(x, m = 10, n = 5)
y

Output:

 [1] 0.0003330003 0.0006660007 0.0009990010 0.0016650017 0.0023310023
 [6] 0.0033300033 0.0043290043 0.0059940060 0.0076590077 0.0099900100

Example 2:

# R Program to compute the value of
# PDF over Wilcoxonrank Sum Distribution

# Creating a sequence of x-values
x <- seq(1, 50, by = 1)

# Calling dwilcox() Function
y <- dwilcox(x, m = 30, n = 10)

# Plot a graph
plot(y)

Output:
