How to use spatial_markov model by adopting my own data #193

Hi, everyone, recently i use the pysal package to implement the spatial_markov. I notice the struction document adopt the "us48.gal", however, the document doesn't give how it form. So, there i have two questions needed to answer. (1), how i get the us48.gal, in other word, how is the us48 file formed? (2), i want to use the spatial_markov by importing my own data, how should i do? I so looking forward to receiving your answer. The official document has listed as following: https://giddy.readthedocs.io/en/latest/MarkovBasedMethods.html

Hi @Daydreamerla, thank you for your interest in using spatial Markov methods. Related to your questions:

us48.gal is a spatial weight file. You can use libpysal to generate a spatial weight object that can be used in your analysis. You may read the GDS book to learn more about spatial weights and how to construct different types of spatial weights using PySAL.
You will need to organize panel data in the form of a n by t numpy array and pass it to Spatial_Markov as the first argument.
