Illuminating Statistical Analysis Using Scenarios and Simulations

This looks like an interesting textbook for an introductory statistics course. I did not see a code repository associated with the book though.

Using raster data in Netlogo

I am trying to replicate the procedure described on page 111-114 in AGIS. The generated clipped population data file cannot be read into NetLogo. After some digging, here is the problem and the solution is really simple: just add '-co force_cellsize=true' to the text box for additional command-line parameters.

I enjoyed reading the book Agent-Based Modeling & Geographical Information Systems. I first got interested in agent-based modeling around 1999. At that time, the only software platform for this kind of modeling is Mathematica. Now with free and open source software like NetLogo, it is much easier to translate ideas into executable code and see the results.

A large number of agent-based models have been developed. OpenABM is an online repository for such models, the majority of which were developed in NetLogo.
