Polynomial Formula

[Hans Schubert]

Good morning.

I would like to generate a new variable that computes the polynomial equation for the trendline in the picture. Looked up exp, but having trouble applying it to my formula.

Thanks

Okay got it now...

gen wanted11 = (3*10^-5 * var1^2) - (0.0058 * var1) +(0.0877)
