Full Changelog: v2.4.3...v2.5.0

Dependency bug fix release

This fixes a minor (breaking) bug for environments without the pygeos package. It makes the pygeos package a soft dependency for functions in the esda.shape and esda.map_comparison modules. If you intend to use functionality from those modules, you will need to install pygeos. Using functions from those modules without having pygeos installed will generate an ImportError or ModuleNotFoundError, depending on the configuration for the installation.

Version 2.4.0: Map Comparisons and Shape Statistics

Changes

Version 2.4.0 (2021-07-26)

This version merges two large new sets of functionalities:

• map correspondence measures in esda.map_comparison
• shape statistics in esda.shape

Contributors to this release include

• @martinfleis
• @knaaptime
• @jGaboardi
• @sjsrey
• @ljwolf

Version 2.3.6 (2021-01-20)

We closed a total of 9 issues (enhancements and bug fixes) through 4 pull requests, since our last release on 2021-01-20. The major enhancements for this release include:

• Integration of the work of @jeffcsauer's 2020 GSOC project. This adds tons of new statistical estimators, such as:
  • the local heteroskedasticity estimator, esda.LOSH
  • local geary and multivariate geary estimators, esda.Geary_Local and esda.Geary_Local_MV
  • local join counts in univariate, bivariate, and multivariate flavors, esda.Join_Counts_Local, esda.Join_Counts_Local_BV, and esda.Join_Counts_Local_MV.
• "analytical" moments for Moran's I for replication/comparison to R. Forms are provided in Sokal 1998.

esda 2.3.1

This is a small bug fix release for an issue on pypi.

See release notes for 2.3.0 for detailed functionality in the latest esda.

esda 2.3.0

esda

ESDA is an open-source Python library for the exploratory analysis of spatial data. A subpackage of PySAL (Python Spatial Analysis Library), esda includes methods for global and local spatial autocorrelation analysis. See the tutorial for use cases.

Version 2.3.0 (2020-07-05)

Major Enhancements

• Highly performant multi-core, numba-based conditional permutation inference for local autocorrelation statistics (#116)
• Adbscan: an extension of the original DBSCAN algorithm that creates an ensemble of solutions generated by running DBSCAN on a random subset and "extending" the solution to the rest of the sample through nearest-neighbor regression (see Arribas-Bel, Garcia-Lopez & Viladecans-Marsal, 2020 for more details). (#120)
