The Coursera Machine Learning course just started (I assume you could still join). I just finished the second week (I'm trying to keep a week ahead due to the somewhat unpredictable nature of my schedule lately), and have been enjoying it so far.

The first couple weeks are all about univariate and multivariate linear regression (as well as an optional linear algebra refresher on matrix operations).

I second this course; I took it when it was put on in 2011 in association with Stanford, and called the "ML Class" - its success was the catalyst for the creation of Coursera.
