Learning to Rank by Causal Effects Without Data to Accurately Estimate Causal Effects
Decision makers often care about the causal effect to select the top customers in a specific treatment, we propose a framework on how to do this even when the data does not lend itself to accurately estimate causal effects.

Posterior Inference on Shallow Infinitely Wide Bayesian Neural Networks under Weights with Unbounded Variance
We propose a method to do posterior inference on neural networks that are infinitely wide, using priors that have unbounded variance.

SURE-tuned Bridge Regression
Bridge is a regularization technique that can consume a lot of time when the number of covariates is much larger than the number of observations. We propose a non-iterative method to reduce this timing without losing statistical prediction power.

Demographic Modeling via 3-dimensional Markov Chains
We propose a new model for understanding and prediction of demographic modeling, using Markov Chains. We apply it to an institution in Costa Rica.
