No project description provided

gwlearn

Geographically weighted modeling based on scikit-learn.

The aim of the package is to provide implementations of spatially-explicit modelling.

Status

Current development status is early beta. API of the package can change without a warning. Use with caution.

Features

gwlearn provides a framework for prototyping geographically weighted extensions of regression and classification models based on scikit-learn and libpysal.graph and a subset of models implemented on top of this framework. For example, you can run geographically weighted linear regression in a following manner.

import geopandas as gpd
from geodatasets import get_path

from gwlearn.linear_model import GWLinearRegression


gdf = gpd.read_file(get_path('geoda.guerry'))

adaptive = GWLinearRegression(
    bandwidth=25,
    fixed=False,
    kernel='tricube'
)
adaptive.fit(
    gdf[['Crm_prp', 'Litercy', 'Donatns', 'Lottery']],
    gdf["Suicids"],
    geometry=gdf.representative_point(),
)

For details, see the documentation.
