pf()
function in R Language is used to compute the density of F Cumulative Distribution Function over a sequence of numeric values. It also plots a density graph for F Cumulative Distribution.
Syntax: pf(x, df1, df2)
Parameters:
x: Numeric Vector
df: Degree of Freedom
Example 1:
# R Program to compute # Cumulative F Density # Creating a sequence of x-values x < - seq( 1 , 30 , by = 2 )
# Calling pf() Function y < - pf(x, df1 = 2 , df2 = 3 )
y |
Output:
[1] 0.5352420 0.8075499 0.8891420 0.9258675 0.9460051 0.9584308 0.9667275 [8] 0.9725899 0.9769124 0.9802073 0.9827867 0.9848509 0.9865331 0.9879255 [15] 0.9890935
Example 2:
# R Program to compute # Cumulative F Density # Creating a sequence of x-values x < - seq( 1 , 30 , by = 0.2 )
# Calling pf() Function y < - pf(x, df1 = 3 , df2 = 7 )
# Plot a graph plot(y) |
