What is the primary purpose of applying a PowerTransformer with the Box-Cox method?

Accepted Answer

The Box-Cox transformation is a power transformation used to stabilize variance and make data follow a normal distribution. It is specifically designed for positive data. It does not handle missing values, reduce dimensionality, or encode categorical variables; its sole purpose is to improve the normality of the distribution to satisfy assumptions of various statistical models.
