st: partial F test
Today in the class we approached the partial F test in
linear regression. The examples have been done in JMP
(that I do not like), but I would like to use STATA
instead. The questions are:
1) Is possible to build a "parent" model (only b0)
without creating another dataset ?
2) How to perform a partial F test in STATA ?
3) Is possible to temporarily exclude some observation
(potential influencing points) and run again the model
without them and without the necessity to create a new
dataset ? I know, this question is not directly
related to the partial F test, but it is critical to
me, just to quickly assess the outliers in the model.
Thank you always
