Reproducibility in data science:

statistical methods and applications

 

The goal of this fast-paced course is to expose PhD-level statistics and machine learning students to current research topics in statistical inference for large-scale data sets, focusing on methods with finite-sample frequentist guarantees.
This work is motivated by the growing reliance of many applied fields on the automatic analysis of large amounts of data in order to make scientific discoveries and inform high-stakes decisions.
In particular, there is growing awareness of a widespread reproducibility crisis in science, and novel statistical methods are needed to ensure that reported discoveries are reproducible and are not spurious discoveries resulting from the multiple-comparisons problem (“data snooping”).
We will begin by introducing the frequentist multiple hypothesis testing problem and exploring a variety of general methods for addressing it.
Next, we will frame the model selection problem as a multiple hypothesis testing problem and explore some of the inferential challenges and recent solutions in this setting.
We will conclude by exploring how conditional independence testing relates to causality and discussing how to calibrate arbitrary machine learning algorithms to ensure valid predictive inference.
