statsmodels.omni_normtest() in Python

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)

Confidence and Prediction Intervals with Statsmodels

In statistical analysis, particularly in linear regression, understanding the uncertainty associated with predictions is crucial. Confidence intervals and prediction intervals are two essential tools for quantifying this uncertainty. Confidence intervals provide a range within which the mean of the

Z score for Outlier Detection - Python

Z score (or standard score) is an important concept in statistics. It helps to understand if a data value is greater or smaller than the mean and how far away it is from the mean. More specifically, the Z score tells how many standard deviations away a data point is from the mean. Z score = (x -mean
