[Equest-users] Performance (curve) anxiety

Performance curves are defined by an INPUT-TYPE of COEFFICIENTS or DATA. I am creating several performance curves based on manufacturer data points, but would like to define them with COEFFICIENTS to save space in the input file.
Can someone walk me through a method to determine coefficients in Excel, or using another add-in or program, for the following CURVE-FIT TYPEs?
TYPE = BI-LINEAR-T
TYPE = BI-QUADRATIC-T
TYPE = CUBIC
Yes, eQUEST generates the coefficients when you enter data points, but I see no way to copy them to then turn around and define the curve using the coefficients.
Thanks,
Bill
