Standard statistical tests

Adding a page with snippets for commonly used statistical tests, like group comparisons, enrichment and linear regression. Meant to be a quick resource, not a comprehensive one.

Tests that could be added:

• Mann-Whitney
• Binomial/Multinomial exact tests
• G-test
• Linear regression

We could also add:

• T-test
• Multiple testing correction of p-values
• Permutation tests to compute empirical p-values

Also, use the entries to explain when it is more convenient to use one test or another
