Data Science
This rubric covers the use of statistical tools working on large datasets to create models and derive inferences, as well as coverage of the field in its entirety. This differs from machine learning primarily in that the latter focuses on functional gradient analysis or neural networks (kernels) to derive models.
Choosing the Correct Statistical Test
In a previous blog post, I created a flow chart showing how to choose a statistical test from a dozen different tests. While researching the… Read More »Choosing the Correct Statistical Test
