Shortnames.R

This is a simple R program I wrote that shortens the names of columns in a data-frame.
When working with large datasets from the worldbank, I found that many of their column names, while descriptive, were annoying long,
This shortens each column name according to a length determined by the user .

Henderson.R

This is a R function which
executes the 2005 Henderson and Ullah non-parametric random effects
estimator. As a caution, I have not finished testing it, and it
should be considered in draft form.

SPRE.R

The main function here is used to complete
a semi-parametric (univariate non-parametric with linear controls) kernel
density regression for panel data in a random effects model.
