WebDec 22, 2014 · 4. Polynomial regression is in effect multiple linear regression: consider X 1 = X and X 2 = X 2 -- then E ( Y) = β 1 X + β 2 X 2 is the same as E ( Y) = β 1 X 1 + β 2 X 2. As such, methods for constructing confidence intervals for parameters (and for the mean in multiple regression) carry over directly to the polynomial case. WebIn this paper, we examine two widely-used approaches, the polynomial chaos expansion (PCE) and Gaussian process (GP) regression, for the development of surrogate models. The theoretical differences between the PCE and GP approximations are discussed.
