where k=1,2,...,p-1, within the model, in order to determine if that individual parameter
should be dropped from the model.
We want to first test each coefficient,
where k=1,2,...,p-1, within the model, in order to determine if that individual parameter
should be dropped from the model.
Hypothesis Tests:
-->
can be dropped from the model
-->
cannot be dropped from the model
Given a Model:
For Testing Each
:
-->
same t testing as simple linear regression
= area in each tail
Now let's look at an example.
