Zeger and Liang (1992) allege that regression parameter estimates from transition models tend to be smaller in absolute value than regression parameter estimates from marginal models. This statement is true in typical longitudinal data situations for the relation between the true parameters of the marginal and transition model. However, under the assumption of a transition model the Generalized...

To explore human deviations from Bayes’ rule in numerically explicit problems, prior and likelihood probabilities or frequencies are manipulated and their effects on posterior probabilities or surprisals are measured. Results show that people use both priors and likelihoods in Bayesian directions, but the effect of likelihood information is stronger than that of prior information. Use of freque...

Methods for group comparisons using predicted probabilities and marginal effects on probabilities are developed for regression models for binary outcomes. Unlike approaches based on the comparison of regression coefficients across groups, the methods we propose are unaffected by the identification of the coefficients and are expressed in the natural metric of the outcome probability. While we d...

This paper evaluates how anticipated changes in household debt associated with the leveraged purchase of housing a ects consumption. I build a heterogeneous agent model, calibrated to match the distribution of income and wealth within the US economy, in which households are subject to uninsurable income shocks and can save in both liquid and illiquid assets. I show that the marginal propensity ...

In this study, magnesium composites with nano-size boron nitride (BN) particulates of varying contents were synthesized using the powder metallurgy (PM) technique incorporating microwave-assisted two-directional sintering followed by hot extrusion. The effect of nano-BN addition on the microstructural and the mechanical behavior of the developed Mg/BN composites were studied in comparison with ...

The study was to evaluate the marginal leakage of wet or dry dentin condition after restoration on short-term. In the study we used Photobond adhesive system and Single Bond adhesive system. The specimens were prepared from premolars. A class V cavity was prepared at the CEJ with a high-speed hand piece and #010 round diamond point. The cavity's walls and floors were etched with phosphoric acid...

High vitamin A (VA) intakes have been correlated with increased risk of bone fracture. Over 50% of the U.S. adult population reports use of dietary supplements, which can result in VA intakes . 200% of the RDA. In this study, 2 experiments were designed to determine the effect of dietary VA on cortical and trabecular bone properties and resistance to ex vivo fracture. In Expt. 1, we investigate...

We consider the entanglement marginal problem, which consists of deciding whether a number reduced density matrices are compatible with an overall separable quantum state. To tackle this we propose hierarchies semidefinite programming relaxations set state marginals admitting fully extension. connect completeness each hierarchy to resolution analog classical problem and thus identify relevant e...
