Вычислить значение кумулятивной функции распределения F в программировании на R - функция pf ()
Опубликовано: 17 Февраля, 2022
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-valuesx <- seq(1, 30, by = 2) # Calling pf() Functiony <- pf(x, df1 = 2, df2 = 3)y |
