Web1 dec. 2024 · We implemented the (AIC-based) constant weights combination rule, as well as the (deviance-based) probabilistic weights combination rule. At each draw t, the model-averaged prediction y ∼ t was set to y ̂ l t with probability λ l [t]. For the constant weights rule: λ l t = w l ∼, where the constant AIC-based weights were reported in Table 2.

WebTheoutput menu for the stdyx; option is included to acquire standardized regression coefficients and R-squared values. (The stdyx; option produces coefficients standardized on both y and x, but other types of standardization are available and can are requested using the standardized; option.) WebThe criterion used is. AIC = - 2*log L + k * edf, where L is the likelihood and edf the equivalent degrees of freedom (i.e., the number of free parameters for usual parametric …
WebFor m3 the AIC is slightly worse if we drop any of the 3 main effects. Also, if I try to include both school.factor and any other main effect variable I get a warning that the fixed-effect matrix is rank deficient so they drop the additional columns/coefficients, always just leaving me with school.factor.
