Forward Stepwise regression - what is the F-to-Enter

[emily c]

I am using the Multiple Regression tool > Forward stepwise regression in Statistica.

It is not clear to mehow the F-to-Enter and F-to-remove values are coded in the software. Is the model definition window expecting a P-value (tail probability value) in which case I should put 0.05for F to enter and 0.1 for F to remove if I want to consider only variables with a significant p-value; or is the model expecting a F-value, in which case the default value is 3.8416, corresponding to a tail probability value of 0.05 for F-to-enter

Thanks!
