transform_data: transform_data

In keyuchen886/OLSregression: Ordinary Least Square regression

Description

In linear regression, or in most of machine learning models, it's import to encode your categorical data. In this transform_data function, we encode categorical variable by creating n-1 new variables as indicator, and the last one is the base level. For example, if a feature sex has only two type: male or female, then we will generate Sexmale feature, which is 1 if the sex is male, 0 otherwise. In fact, this function is used internally in linear_regression() function to change dataframe.
