DEAPack: A Data Envelopment Analysis Package

DEAPack is a Python package designed for Data Envelopment Analysis (DEA). Its comprehensive toolset allows for efficient handling of various DEA models, including those that account for undesirable outputs.

Installation

Install the package by pip,

pip install DEAPack

Or install the package by conda,

conda install DEAPack

Usage

A brief example is provided below. For more information, please refer to the documentation and example notebooks.

# import the module
from DEAPack.model import DEA
from DEAPack.utilities import load_example_data

# load the example dataset
data = load_example_data()

# initilise a DEA model
model = DEA()

# specify the DEA model
model.DMUs = data['region']
model.time = data['year']
model.x_vars = data[['K', 'L', 'E']]
model.y_vars = data[['Y']]
model.b_vars = data[['CO2']]

# solve the DEA model
model.solve()

# get estimated efficiencies
results = model.get_efficiency()
