WebThe performance of AALasso was compared with that of ALasso and Lasso. PK data was simulated in four set-ups from a one-compartment bolus input model. Covariates were created by sampling from a multivariate standard normal distribution with no, low (0.2), moderate (0.5) or high (0.7) correlation.

Webinactive cointegrating group cannot all survive Alasso's selection. This nding suggests a straightforward method of reclaiming the desirable oracle property: simply run a second-round Alasso on the ariablesv selected by the rst-round Alasso.

WebOur proposed method is based on an estimating equation with the first derivative of the ALASSO penalty function. The rest of the article is organized as follows. Section 2.1 presents a variable selection procedure for model (1) via a penalized estimating function. The asymptotic properties of the proposed estimators are established in Section 2.2. Webthe ALASSO, suppose for the time being, that the first po components of the true regression parameter β are nonzero and the last (ρ — po) components are zero, where 1 < po < p.
