Nested random effects assume that there is … WebAbstract: A study of random-dopant-fluctuation (RDF) effects on the trigate bulk MOSFET versus the planar bulk MOSFET is performed via atomistic 3D device simulation for devices with a 20 nm gate length. For identical nominal body and source/drain doping profiles and layout width, the trigate bulk MOSFET shows less threshold voltage (V th) lowering and …

Webstandard fixed-effects, or within, estimator is a workhorse in empirical studies that rely on linear panel data models. When the partial effects of interest are on time-varying covariates, fixed-effects estimation is attrac-tive because it allows for additive, unobserved heterogene-ity that can be freely correlated with the time-varying covariates.

WebThe use of fixed (FE) and random effects (RE) in two-level hierarchical linear regression is discussed in the context of education research. We compare the robustness of FE models with the modelling flexibility and potential efficiency of those from RE models. We argue that the two should be seen as complementary approaches.
