What This Document Is
This document presents lecture notes from a Statistical Genetics course (STATISTICS 246) at the University of California, Berkeley. It delves into the application of linear modeling techniques for identifying *cis*-regulatory modules – key elements controlling gene expression. The material explores how statistical methods can be used to uncover relationships between genomic features and gene activity levels, offering a focused look at approaches beyond traditional motif finding. It builds upon previously discussed statistical modeling concepts.
