outkast 0.1.0

Base Classifier

We start by providing a base model for last_name that gives the Bayes optimal solution providing the proportion of SC, ST, and Other with that last name. We also provide a series of base models where the state of residence is known.

Installation

We strongly recommend installing outkast inside a Python virtual environment (see venv documentation)

pip install outkast

            column.
        namecol (str or int): Column's name or location of the name in
            DataFrame.
        state (str): The state name of SECC data to be used.
            (default is None for all states)
        year (int): The year of SECC data to be used.
            (default is None for all years)

    Returns:
        DataFrame: Pandas DataFrame with additional columns:-
