comment Creating Irregular ellipses using SQL Spatial 2012 Geometry
This isn't enough information to draw an ellipse unless you have a measure of the eccentricity and/or orientation. Multiple ellipses can be generated through the same set of max and min coordinates.

comment Import arcpy using PyScripter or IDLE gives No module named RuntimeError?
FYI on my windows machine I've had to play around with the environment variables repeatedly to curtail this problem of not being able to find whatever python library.

comment Eye-friendly colours for long periods of work
I haven't had to do tedious digitizing like this @Jens, so I do not have experience in that regard. But the printed maps with a dark background I've had good experience in user groups disseminating crime maps with dark backgrounds (community meetings - often with elderly people in darker lit rooms).

comment Interpreting Moran's I results
Instead of posting a screen shot of the excel spreadsheet, you should just include it in text using the code formatting tools. Here one could reproduce your example alot easier if you took that step.

comment Literature on bias in spatial weights matrix
I don't address the differing populations part of the question, as that is more about the model you estimate than it is about the spatial weights matrix specifically. Certain types of spatial models deal with differing populations pretty explicitly (e.g. Bayesian CAR models using the population as a denominator).

comment GWR Model with Zero Intercept
This is likely a bad idea, see a post on the stats site about removing the intercept. If your data are counts you might consider a different type of regression model. The logic behind GWR is perfectly adaptable to different types of regression models, e.g. Poisson or Logistic (or even quantile regression). See the spgwr R package for an implementation. Also removing the intercept won't necessarily restrict the predictions to be above 0 anyway.

comment Arcpy in Python Plugin for SPSS
As of V22 SPSS comes automatically installed with Python, and its version will match your SPSS version. Maybe you can try to download Geoprocessing for 64 bit and see if you can point SPSS's python to that location.

comment Arcpy in Python Plugin for SPSS
I doubt the Python install with ArcGIS is 64 bit - so if you have 64 bit SPSS that won't work anyway.

comment Arcpy in Python Plugin for SPSS
No, you can just change the location through the menus. Edit -> Options -> File Locations. I don't believe there is native command syntax to do this.
