We covered ... Corrected errors in canonical correlation finished Principal Components Analysis More Principal Components Exploratory Factor Analysis introduced confirmatiory factor analysis 1Nov7 -- I have saved the discriminat analysis program we worked on in class to here. I cleaned it up some and added annotation. I also renamed matrix t to X which better fits the class notes. 7Nov07 -- week 6. We covered ... Classification of Observations Canonical Correlation Analysis The Big Picture started Principal Components Analysis 28Oct07 I will have a Tuesday office hour again this week from 12:30 to 1:30. I will try to make every Tuesday from 12:30-1:30. 31Oct07 -- week 5. We covered ... Hypothesis Testing: Equality of Covariance Matrices Discriminant Analysis Profile Analysis 22Oct07 Oops, I made an error while updating the X matrix for assignments #2. It is fixed now. 22Oct07 I understand that students are having difficulty with assignment #2 so I will hold additional office hours, this week, to help students who are having problems: M 12:30-1:30 and T 12:30-1:30. 24Oct07 -- week 4. We covered the following units... Hypothesis Testing: k-Groups Matrix Operations II Matrix Operations III 17Oct07 -- week 3.
