simpute-py 0.1.1

A python package for simple data imputation

What does it do?

Have you ever had a time when your missing data was holding you back? Well then this package is for you!

Our python package for simple data imputation will allow you to quickly and seamlessly impute any missing data (be numeric, categorical, date/time or boolean values) using any large datasets.

All you have to do is follow these simple 4 steps:

1. Import the package and the data you wish you impute
2. Select the function and method for imputation (this will depend on the data type - read the usage section below for more details)
3. Hit run
4. Save your newly imputed dataset

Our package will help simplify all your imputation needs so your data is ready when you need it!

Installation

$ pip install simpute_py

Usage and Examples

We have four main functions dealing with each data type:

• Num_imputer: This function fills in the empty values of a numeric column with values derived from your selected imputation method. Your options for method include knn (autogenerated values based on KNN), mean, median and mode.
• Cat_imputer: This function fills in the empty values of a categorical column with values derived based on most frequent (mode) category.
• Bol_imputer: This function fills in the empty values of a boolean column with values derived using most frequent (mode) boolean value.
• Date_imputer: This function fills in empty values of a date column with median point of the range of dates in that column.

To get started first install our imputation functions:

from simpute_py.bol_imputer import bol_imputer #For imputing on boolean columns
from simpute_py.cat_imputer import cat_imputer #For imputing on categorical columns
from simpute_py.date_imputer import date_imputer #For imputing on date columns
from simpute_py.num_imputer import num_imputer #For imputing on numerical columns

To run to the function, simply enter the following:

import pandas as pd

#Load test data from home directory
test_df = pd.read_csv('tests/tesla_deaths_mini.csv')

#Test functions
test_df = bol_imputer(test_df, "Driver")
test_df = cat_imputer(test_df, "Country")
test_df = date_imputer(test_df, "Date")
test_df = num_imputer(test_df, "Deaths")

print(test_df)

Place in the Python Ecosystem

Currently, there are many other ways you can impute a dataset, using various functions build within Python, but this packages it neatly into one place and simplifies the process. We do have other packages you can use such as AutoImpute and MIDASpy. However our package aims to provide functionality not provided in either package and for more general audience use.
