View Full DocumentYou are hired as a junior analyst by the east coast chain,
Pizza
π
, to analyze several models for annual
pizza consumption by individuals.
Consider the following simple regression model.
Model 1:
E(P)
=
0
β
+
1
M
where
P
= annual pizza consumption expenditures ($)
M
= annual income (thousand $)
Below are your EViews regression results.
While you were analyzing your results you happened to be eating pizza (with extra
sauce) and unfortunately splattered sauce on your computer printout.
Thus certain values are unavailable because they’re
unreadable through the splat marks. Rather than go back to your computer, you decide you are confident enough to determine
certain values by hand and a simple calculator. After all, you are a relatively ‘smart’ analyst (even though you’re a sloppy eater at
times
: ).
