# Multivariable non-linear (?) regression in STATA

Hello,

Thank you for this wonderful forum!
I'm very new to statistics and to the software STATA, so I apologize if my question is too straightforward.
I'm trying to find the coefficients (a0, a1 ... o1) in the following equation:
cost = {a0}* m + {a1}* m^2+{b0}* l+{b1}* l^2+{c0}* h+{c1}*h^2+{g0}* r+{g1}* r^2+{j0}* b+{j1}* b^2+{k0}* s+{k1}* s^
> 2+{o0}* d+{o1}* d^2

I have several values for several years for the cost and the variables m, l, h, r, b, s, d, e.

What is the relevant method to find these coefficients, and what is the corresponding function in STATA that can return the coefficients?

Thank you in advance, and sorry again if the question is too straightforward.

Sincerely,
NS
