Adjustments and Corrections

This week, I have made several small adjustements to the following:

C.3.4 lesson.  Exercise 2.  There was a X/5 – 1 that should have been a 1 + X/5.

D.1.2 and D.1 summary sheet: Added alternative title for the Model matrix X, a.k.a. the Design matrix.   Also, added a note to the summary sheet that the column of ones in X corresponds to the interecept parameters.

D.2.6 problems 2, 4, 5, 6 all used a chart that showed one variable having 2 degress of freedom which should have been only 1. This is corrected. This issue had no bearing on the problem at hand.

D.3.4 problem #6 was missing some factorial signs in the Poisson density formula used to compute the MLE.

My guess is that these will cause no significant difficulties, but you may want to grab a new copy of the D.1. summary sheet.
