statsmodels.omni_normtest() in Python (original) (raw)

Last Updated : 22 Apr, 2020

With the help of **statsmodels.omni_normtest()** method, we can get the omnibus test for normality and we use chi^2 score for this statsmodels.omni_normtest() method.

Syntax : statsmodels.omni_normtest(array) Return : Return the omnibus test for normality.

**Example #1 :**In this example we can see that by using statsmodels.omni_normtest() method, we are able to calculate the omnibus test for normality by using chi^2 score in this method.

Python3 1=1 `

import numpy and statsmodels

import numpy as np from statsmodels.stats.stattools import omni_normtest

g = np.array([1, 2, 3, 4, 5, 6, 7, 8])

Using statsmodels.omni_normtest() method

gfg = omni_normtest(g)

print(gfg)

`

Output :

NormaltestResult(statistic=1.7004056883060088, pvalue=0.42732824212143383)

Example #2 :

Python3 1=1 `

import numpy and statsmodels

import numpy as np from statsmodels.stats.stattools import omni_normtest

g = np.array([1, 2, 3, 4, 5, 6, 7, 8, 9, 10])

Using statsmodels.omni_normtest() method

gfg = omni_normtest(g)

print(gfg)

`

Output :

NormaltestResult(statistic=2.02697581498966, pvalue=0.362950830342156)
