WebMar 13, 2024 · P equals the number of degrees-of-freedom for regression. A third value D can be calculated by D = N − P. For model A, this equals 1, and for model B, it equals 0. D is called the degrees-of-freedom for the lack-of-fit. If there are no replicates (as discussed below), this also equals the degree-of-freedom for the residuals.
