outkast: estimate caste by last name, year, and state

Using data on more than 140M Indians across 19 states from the `Socio-Economic Caste Census `__ (parsed data `here `__), we estimate the proportion `scheduled caste, scheduled tribe, and other` for a particular last name, year, and state.

Why?
====

We provide this package so that people can assess, highlight, and fight unfairness.

How is the underlying data produced?
====================================

1. The `script `__ downloads the `clean version `__ of the SECC posted `here `__.

2. `Produce base data frame `__ and `infer last names `__

  * remove names with non-alphabetical characters
  * remove records with missing last names
  * remove < 2 char last names
  * remove rows with birth_date < 1900
  * last name shared by at least 1000 hh

3. `Group by last name, state, and year `__ and produce the `underlying data `__

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

    >>>
    >>> help(secc_caste)
    Help on method secc_caste in module outkast.secc_caste_ln:

    secc_caste(df, namecol, state=None, year=None) method of builtins.type instance
        Appends additional columns from SECC data to the input DataFrame
        based on the last name.

        Removes extra space. Checks if the name is the SECC data.
        If it is, outputs data from that row.

        Args:
            df (:obj:`DataFrame`): Pandas DataFrame containing the last name
                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:-
                'n_sc', 'n_st', 'n_other',
                'prop_sc', 'prop_st', 'prop_other' by last name
