Maxwell Distribution in Statistics using Python

The scipy.stats.maxwell(), known as the Pareto of the Second Kind, defines the Maxwell continuous random variable. It is an instance of the rv_continuous class inherited from the generic methods. It completes the techniques by adding details specific to this distribution.

The Parameters included in the scipy.stats.maxwell() are:

  • q: it is referred to as the probability of the lower and upper tail
  • x: it refers to the quantiles
  • loc: it is used to refer to the location parameter. This parameter is optional
  • scale: it refers to the scale parameter. This parameter is optional
  • moments: It is composed of different letters ['msvk']:
    • 'm': mean
    • 'v': variance
    • 's': Fisher's skew
    • 'k': Fisher's kurtosis

By default, it is 'mv' (mean and variance)

  • Size: It defines the shape or random variates. It is a tuple of integer data type. It is an optional parameter.
  • Results: It returns the Maxwell continuous random variable.

The scipy library in Python offers different packages for calculating the Maxwell Distribution in Statistics named scipy.stats. This package provides a module named Maxwell which can be used for the Maxwell Distribution.

The probability density function for Maxwell distribution

Maxwell Distribution in Statistics using Python

The probability density function defined is the standardized form. We use the loc and scale parameters to shift and scale the distribution. The shifting of the location does not make it a noncentral distribution. maxwell.pdf(x, loc, scale) is exactly equal to maxwell.pdf(y) / scale with y = (x - loc) / scale.

Importing Maxwell library in Python

Let's understand the concept of the Maxwell distribution of Statistics using Python.

Program 1: A program to create Maxwell Continuous Random Variable

Code:

Output:

Random Variable : 
 <scipy.stats._distn_infrastructure.rv_continuous_frozen object at 0x000001E2E634D690>

Explanation:

In this, we have imported the Maxwell module. Then we assign two random variables, then using the maxwell() function, we will print the continuous Maxwell distribution of the random variables.

Program 2: A program to create Maxwell Continuous Variates and Probability Distribution.

Code:

Output:

Random Variates :
