The Distribution of Stochastic Shrinkage Parameters in Ridge Regression [PDF]
In this article we derive the density and distribution functions of the stochastic shrinkage parameters of three well-known operational Ridge Regression estimators by assuming normality. The stochastic behavior of these parameters is likely to affect the

Asymmetry of the Ferroelectric Phase Transition in BaTiO3
Advanced Materials, EarlyView.Phase transitions are typically assumed to behave identically in forward and reverse. This work shows that in the ferroelectric material barium titanate this is not true: heating drives an abrupt, first‐order jump, while cooling gives a smooth, continuous change.

A Solid State Zwitterionic Plastic Crystal With High Static Dielectric Constant
Advanced Materials, EarlyView.Developing solid high dielectric constant materials has been a research focus in the energy storage field. In this research, we discovered a zwitterion with a plastic crystal phase. Due to the short‐range degree of freedom of the dipole moment for this zwitterion, a relatively high static dielectric constant has been achieved in its solid state ...

Handling multicollinearity and outliers using weighted ridge least trimmed squares [PDF]
, 2014 Common problems in multiple linear regression models are multicollinearity and outliers. In this paper, we will propose a robust ridge regression. It is based on weighted ridge least trimmed squares (WRLTS).

Advanced Materials, EarlyView.Scalable bottom‐up fabrication of Fe3O4 nanodots on Nb:SrTiO3 using anodic alumina templates enables long‐range ordered arrays with diameters down to 30 nm. STEM highlights the epitaxial growth of Fe3O4 films on Nb:SrTiO3. Complementary polarized neutron reflectometry (PNR) and X‐ray magnetic circular dichroism (XMCD) measurements on continuous films ...

Computational Journal of Mathematical and Statistical SciencesThe multicollinearity problem occurrence of the explanatory variables affects the least-squares (LS) estimator seriously in the regression models. The multicollinearity adverse effects on the LS estimation are also investigated by many authors.

Advanced Materials, EarlyView.Magnetic tunnel junctions (MTJs) using MgO tunnel barriers face challenges of high resistance‐area product and low tunnel magnetoresistance (TMR). To discover alternative materials, Literature Enhanced Ab initio Discovery (LEAD) is developed. The LEAD‐predicted materials are theoretically evaluated, showing that MTJs with dusting of ScN or TiN on ...

Divide and Conquer Kernel Ridge Regression: A Distributed Algorithm with Minimax Optimal Rates [PDF]
, 2014 We establish optimal convergence rates for a decomposition-based scalable approach to kernel ridge regression. The method is simple to describe: it randomly partitions a dataset of size N into m subsets of equal size, computes an independent kernel ridge
