Scale Evaluation with Exploratory Structural Equation Modeling and Simultaneous Adjustment for Acquiescence Bias

There is continued debate about the appropriateness of Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) for scale evaluation and latent variable modeling more generally. This study seeks to combine the strengths of EFA, namely flexible evaluation of item-factor structures, while using one of the unique strengths of CFA, the simultaneous adjustment for common method bias ...

Bias Adjustment for a Nonparametric Entropy Estimator

Zhang in 2012 introduced a nonparametric estimator of Shannon’s entropy, whose bias decays exponentially fast when the alphabet is finite. We propose a methodology to estimate the bias of this estimator. We then use it to construct a new estimator of entropy. Simulation results suggest that this bias adjusted estimator has a significantly lower bias than many other commonly used estimators. We ...

Marginal Mean Weighting Adjustment for Selection Bias

Image matching with scale adjustment

In this paper we address the problem ofmatching two images with two different resolutions: a high-resolution image and a low-resolution one. The difference in resolution between the two images is not known and without loss of generality one of the images is assumed to be the high-resolution one. On the premise that changes in resolution act as a smoothing equivalent to changes in scale, a scale...

Scale–dependent Galaxy Bias

We present a simple heuristic model to demonstrate how feedback related to the galaxy formation process can result in a scale-dependent bias of mass versus light, even on very large scales. The model invokes the idea that galaxies form initially in locations determined by the local density field, but the subsequent formation of galaxies is also influenced by the presence of nearby galaxies that...
