# Python – Nakagami Distribution in Statistics

• Last Updated : 10 Jan, 2020

scipy.stats.nakagami() is a Nakagami continuous random variable. It is inherited from the of generic methods as an instance of the rv_continuous class. It completes the methods with details specific for this particular distribution.

Parameters :

q : lower and upper tail probability
x : quantiles
loc : [optional]location parameter. Default = 0
scale : [optional]scale parameter. Default = 1
size : [tuple of ints, optional] shape or random variates.
moments : [optional] composed of letters [‘mvsk’]; ‘m’ = mean, ‘v’ = variance, ‘s’ = Fisher’s skew and ‘k’ = Fisher’s kurtosis. (default = ‘mv’).

Results : Nakagami continuous random variable

Code #1 : Creating Nakagami continuous random variable

 `# importing library`` ` `from` `scipy.stats ``import` `nakagami  ``   ` `numargs ``=` `nakagami.numargs ``a, b ``=` `4.32``, ``3.18``rv ``=` `nakagami(a, b) ``   ` `print` `(``"RV : \n"``, rv)  `

Output :

```RV :
```

Code #2 : Nakagami continuous variates and probability distribution

 `import` `numpy as np ``quantile ``=` `np.arange (``0.01``, ``1``, ``0.1``) `` ` `# Random Variates ``R ``=` `nakagami.rvs(a, b) ``print` `(``"Random Variates : \n"``, R) `` ` `# PDF ``R ``=` `nakagami.pdf(a, b, quantile) ``print` `(``"\nProbability Distribution : \n"``, R) `

Output :

```Random Variates :
4.258999638050341

Probability Distribution :
[1.85789479e-21 2.46056635e-20 3.04869642e-19 3.53340722e-18

Code #3 : Graphical Representation.

 `import` `numpy as np ``import` `matplotlib.pyplot as plt ``    ` `distribution ``=` `np.linspace(``0``, np.minimum(rv.dist.b, ``3``)) ``print``(``"Distribution : \n"``, distribution) ``    ` `plot ``=` `plt.plot(distribution, rv.pdf(distribution)) `

Output :

```Distribution :

Code #4 : Varying Positional Arguments

 `import` `matplotlib.pyplot as plt ``import` `numpy as np ``    ` `x ``=` `np.linspace(``0``, ``5``, ``100``) ``    ` `# Varying positional arguments ``y1 ``=` `nakagami .pdf(x, ``1``, ``3``) ``y2 ``=` `nakagami .pdf(x, ``1``, ``4``) ``plt.plot(x, y1, ``"*"``, x, y2, ``"r--"``) `
