PySAL 1.7 Release (2014 01 31) - MridulS/pysal GitHub Wiki

On behalf of the PySAL development team, I'm happy to announce the official release of PySAL 1.7.

PySAL is a library of tools for spatial data analysis and geocomputation written in Python. PySAL 1.7, the eight official release of PySAL brings the following key enhancements:

Spatial regression (spreg)

  • Maximum Likelihood estimation of the spatial error model
  • Maximum Likelihood estimation of the spatial lag model
  • Maximum Likelihood estimation of the spatial error model with regimes
  • Maximum Likelihood estimation of the spatial lag model with regimes

Spatial weights (weights)

  • Optimized check for asymmetries in spatial weights
  • Refactoring of weights data structure (removal of read only dictionary)

Regionalization (region)

  • Optimized connected component check

Exploratory Spatial Data Analysis (esda)

  • Two-tailed analytical p-values for Moran's I as new default

among the 176 commits and bug fixes since the last release, 6 months ago.
