It is part of my programme:
rstool(X12,CCU,'purequadratic')
stats = regstats(CCU,X12,'purequadratic')
stats.beta
From function stats.beta I've got 5 coefficients:
224,063250000000
-0,375900000000010
-81,9059250000000
0,0131565000000002
8,80680000000000
I don't know what position have each of them in the equation.
What is the model of equation used automatically in MATLAB?
Is it z=ax^2+bx+cy^2+dy+exy+f?
If yes why I've got only 5 insted of 6 coefficients?
I would like to ask for your help, thank you so much!
Best regards,
Mateusz
