sympy.stats.Rayleigh() in Python

With the help of sympy.stats.Rayleigh() method, we can get the continuous random variable which represents the rayleigh distribution.

Syntax : sympy.stats.Rayleigh(name, sigma)
Where, sigma are real number and sigma > 0.

Return : Return the continuous random variable.

Example #1 :
In this example we can see that by using sympy.stats.Rayleigh() method, we are able to get the continuous random variable representing rayleigh distribution by using this method.

# Import sympy and Rayleigh
from sympy.stats import Rayleigh, density
from sympy import Symbol, pprint

z = Symbol("z")
sigma = Symbol("sigma", positive = True)

# Using sympy.stats.Rayleigh() method
X = Rayleigh("x", sigma)
gfg = density(X)(z)

pprint(gfg)

Output :

2
-z
——–
2
2*sigma
z*e
———–
2
sigma

Example #2 :

# Import sympy and Rayleigh
from sympy.stats import Rayleigh, density
from sympy import Symbol, pprint

z = 0.35
sigma = 2

# Using sympy.stats.Rayleigh() method
X = Rayleigh("x", sigma)
gfg = density(X)(z)

pprint(gfg)

Output :

0.0861703622690834
