Hello Paul,

Yes, I agree. Given the fact that now I only have two paramters left (=being
significant), is this the correct equation (keeping in mind the table
below)?

Y = 4.195 - 0.319 * A  - 0.442 * C + e

What would be e in this case? I have standard erros for each parameter...

Kind Regards,
Karl
