Student Evaluations of Teaching (Mostly) Do Not Measure Teaching Effectiveness
Published:
We showed that student evaluations of teaching are biased against female instructors, and it is not possible to adjust for the bias due to its dependence on many other factors.

Simple Random Sampling: Not So Simple
Published:
We propose several best practices for researchers using PRNGs for simulations, including the wide adoption of hash function based PRNGs.
Nonparametric Risk Attribution for Factor Models of Portfolios
Published:
We explain a two-step process for partitioning the risk of projected returns into contributions from latent factors using nonparametric regression methods.
An Empirical Comparison of Parametric and Permutation Tests for Regression Analysis of Randomized Experiments
