ABSTRACT
So far, we’ve been thinking about regressing one list of numbers on another, but this is only the very simplest use of linear regression in modern molecular biology. Regression can also help us think about the kinds of high-dimensional data vectors that we were considering in the context of clustering and sequence analysis in Chapters 5 and 6. e major way regression is used in this context is when we reinterpret X as a highdimensional set of variables that might explain Y.
