KRLSplots ado package for Stata

This ado file creates plots after estimating a model using Kernel-regularized least squares (KRLS).  You need to obtain the KRLS ado package separately from this. This ado file creates various Lowess plots by regressing the estimated derivatives on the variables in the model.  This was demonstrated and described in this published article:

Hipp, John R., Kevin Kane, and Jae Hong Kim. (2017). “Recipes for Neighborhood Development: A Machine Learning Approach toward Understanding the Impact of Mixing in Neighborhoods.” Landscape and Urban Planning.  164: 1-12.

This krlsplot.ado package determines which variable(s) are most strongly associated with a set of derivatives by regressing the derivatives on the variable and its squared and cubed versions.  The user defines a cutoff r-square value for retaining a particular plot. 

You can download the ado file, the example do file and dataset, and the documentation here.  They are in a zipped file.  Or you can download the krlsplot.ado file directly.

See the KRLSplots_documentation.pdf file for instructions on how to use.

Here is what an example plot looks like.

Graduate Student Seth Williams wins 2019 Gil Geis Award

ILSSC graduate student Seth Williams was awarded the 2019 Gil Geis Award for excellence in research. This award is given to a graduate student who has demonstrated excellence in research. The committee noted that “Williams’ work, which has been published in prominent national journals, involves measures of neighborhood cohesion and integration. In a short period of time, he has become one of the leading authorities in spatial criminology.” Big congrats to Seth!!
