Compute the value of CDF over Studentized Range Distribution in R Programming – ptukey() Function

ptukey() function in R Language is used to compute the value of Cumulative Distribution Function(CDF) over Studentized Range for a sequence of numeric values.

Syntax: ptukey(x, nmeans, df)

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

Example 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

Output:

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

Example 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)

Output:
