Based upon the scatterplot matrix for the seven regressors, comment
on the possibility of multicollinearity between some of the
regressors. Note, scatterplots can also be useful in spotting
outliers and other data anomalies.

This preamble applied to questions 1 & 2 (Based loosely on textbook page 442) Say we are interested in examining the linear relationship between the monthly labour hours required in a hospital (y), the monthly x-ray exposures (x1), monthly occupied bed days (x2), and average length of stay (x3). We gather 10 observations, and input the data into Excel. We obtain the following output Intercept X Variable 1 X Variable 2 X Variable 3 Coefficients 1134.56 0.16 0.27 -147.93 Standard...

A. Issues [1] In addition to damages for one year's notice period, can a trial judge award significant damages for the mere fact of an employee's dismissal, or for the stigma that that dismissal brings? Or for the employer thereafter competing with the ex-employee for the clients, before the ex-employee has got a new job? B. Basic Facts [2] This is an appeal from 2009 ABQB 591 (CanLII), 473 A.R. 254. [3] Usually a judgment recites facts before law. But...
