Pareto Distribution
A distribution following Pareto's law i.e. 80-20 distribution (20% factors cause 80% outcome).
It has two parameter:
- a - shape parameter.
- size - The shape of the returned array.
Example
Draw out a sample for pareto distribution with shape of 2 with size 2x3:
from numpy import random
x = random.pareto(a=2, size=(2, 3))
print(x)Visualization of Pareto Distribution
Example
from numpy import random
import matplotlib.pyplot as plt
import seaborn as sns
sns.distplot(random.pareto(a=2, size=1000))
plt.show()Result:
