•Rayleigh distribution is used in signal processing.
•At unit stddev and 2 degrees of freedom rayleigh and chi square represent the same distributions.

Rayleigh distribution is used in signal processing.

It has two parameters:

scale - (standard deviation) decides how flat the distribution will be default 1.0).

size - The shape of the returned array.

python

from numpy import randomx = random.rayleigh(scale=2, size=(2, 3))print(val_1)

Visualization of Rayleigh Distribution

python

from numpy import randomimport matplotlib.pyplot as pltimport seaborn as sns
sns.displot(random.rayleigh(size=1000), kind="kde")plt.show()

At unit stddev and 2 degrees of freedom rayleigh and chi square represent the same distributions.
