betavariate()
is an inbuilt method of the random
module. It is used to return a random floating point number with beta distribution. The returned value is between 0 and 1.
Syntax : random.betavariate(alpha, beta)
Parameters :
alpha : greater than 0
beta : greater than 0Returns : a random beta distribution floating number between 0 and 1
Example 1:
# import the random module import random
# determining the values of the parameters alpha = 5
beta = 10
# using the betavariate() method print (random.betavariate(alpha, beta))
|
Output :
0.5148685287422776
Example 2: We can generate the number multiple times and plot a graph to observe the beta distribution.
# import the required libraries import random
import matplotlib.pyplot as plt
# store the random numbers in a # list nums = []
low = 10
high = 100
mode = 20
for i in range ( 100 ):
temp = random.betavariate( 5 , 10 )
nums.append(temp)
# plotting a graph plt.plot(nums) plt.show() |
Output :
