LISA (Laboratory for Interdisciplinary Statistical Analysis) provided a series of evening short courses to help graduate students use statistics in their research. The focus of these two-hour courses was on teaching practical statistical techniques for analyzing or collecting data.

April 12, 2010:
Multivariate Methods
Instructors: Nels Johnson and Matt Williams

The goal of this talk is to familiarize those in attendance with some common multivariate methods, such as principal component analysis, factor analysis, Hotelling’s T2, etc. We’ll try to motivate each method by identifying problems where it could be used, what kinds of assumptions are made, what kinds of interpretations they lead to, and some pros and cons of the method. We want this talk to be accessible, however a basic level of understanding of both statistics and matrix algebra will be very helpful to all those in attendance.
