Hi,

I need to use linear regression to make a prediction using 3 independet
valuables.
I went to tools-data analysis--and chose "regression" in the pop-up window.
But, after I got a window for regression, I see only two text boxes to
insert independent variables though I uses 3 variables.

Does anybody know how I can get a data analysis tool which is used for more
than 2 independent valuables?
