(1) Investigate the array-entered LINEST worksheet function for obtaining
regression coefficients (either in worksheet cells or in a VBA routine).

(2) Observe the usual cautions about overfitting the data (which might occur

So, Mike, if I read you correctly, you claim that the coefficients
generated by LINEST could then be passed into VBA equation of the form
y=b + a1x+a2x^2 etc ...
interesting approach, thx ..I'll look into that possibility
