Among Python programmers and data scientists, the common convention is to import Numpy with the alias ‘np‘. You can do that with the following code: import numpy as np If you import Numpy with this alias, you can call the Numpy variance function asnp.var(). ...
While we can use frequencies to calculate probabilities of occurrence for categorical attributes, we cannot use the same approach for continuous attributes. Instead, we first need to calculate the mean and variance for x in each class and then calculate P(x|C) using the following formula: ...
ANOVA using Python (with examples)Permalink ANOVA is a statistical method used for analyzing the differences in means in three or more groups. ANOVA compares the variance between-groups means to the variance within-groups. If the variance between-groups is larger than the within-groups, it sugges...
