Denis -

The top row of the Coefficients section is for the Intercept. Each other row
is for an explanatory variable. In the Regression tool dialog box, if you do
not check the box for Confidence Level, each row contains Lower and Upper
bounds for a 95% interval, followed by duplicate values. If you do check the
box for Confidence Level, and if you enter a specific value like 99%, each
row contains Lower and Upper bounds for a 95% interval and Lower and Upper
bounds for a 99% interval.
