How to perform ANOVA in python?
Anova stands for ANALYSIS OF VARIANCE.
ANOVA is a means that of examination the magnitude relation of systematic variance to unsystematic variance in associate experimental study. Variance within the anova is partitioned off into total variance, variance because of teams, and variance because of individual variations.
The ratio obtained once doing this comparison is known as F-ratio. A unidirectional analysis of variance are often seen as a regression model with one categorical predictor.

We will read california housing data from the drive.
df= pd.read_csv('/content/sample_data/california_housing_train.csv') df.head()
Before applying ANOVA we have to apply OLS on some column particularly.
model=ols('total_bedrooms ~ housing_median_age + total_bedrooms + households',data=df).fit()
Applying ANALYSIS OF VARIANCE on the selected columns of the Dataset.
aov= sm.stats.anova_lm(model, typ =1) print(aov)
