Re: orothogoanl polynomials in ASreml

Thanks Arthur, but I am trying to for mthe prediction equation
 
i..e the a's in
 
y = a0 + a1.x + a2.x^2 + a3.x^3
Regards
 
Craig

Dear Craig,

The .res file contains the polynomial coefficients associated with their
corresponding data values. For intercept and linear, the mapping is
straight forward.

To predict at values not in the data, use the !PVALS qualifier to
specify the additional points.

For PREDICTION in ASReml, you just need to specify the values of the
base variable.

Is that enough?
