PySAL 1.7 Release (2014 01 31)
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:
- 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
- Optimized check for asymmetries in spatial weights
- Refactoring of weights data structure (removal of read only dictionary)
- Optimized connected component check
- 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.
