SAS macros for principal components analysis and correlation matrices

- PCA Bootstrap Confidence Intervals
This program bootstraps relationships among traits by randomly sampling the actual observations in a data set with replacement.

- PCA Randomization Tests
This program tests for significant relationships among variables using randomization. It tests for significant correlations/covariances and significant eigenvalues and eigenvector coefficients from Principal Components Analyses.


Laboratory Protocols

These are the protocols we use in the Tonsor Lab for performing routine procedures. The first draft was often written by undergraduate researchers in the lab, then edited by more experienced lab members. Each time the protocol is used, there is an opportunity for discussion at the weekly lab meeting and for editing. Comments, advice and conversation are most welcome.
