Patient perceptions of health care quality are critical to a health care service provider's long-term success because of the significant influence that perceptions have on the outcome of the healthcare process and on patient behavioral decisions. It is a critical strategy for health care...

Discrepancy measure can be utilized as a uniformity measure for comparing factorial designs. A so-called discrete discrepancy has been used to evaluate the uniformity of factorials. In this paper we give linkages among uniformity measured by the discrete discrepancy, generalized minimum...

The objective of this paper is to study the issue of lower bound of the wrap-around L2-discrepancy value on asymmetrical designs with two and three mixed levels. We present a new lower bound of wrap-around L2-discrepancy, and by numerical simulation and some examples, we show that our lower...

This article develops a new mechanism to foldover designs involving factors with multi-level. By exhaustive search we identify the optimal foldover plans. This paper aims to study the issue of the optimal foldover plans for three-level designs, in view of the uniformity criterion measured by the...

Maximum entropy models, motivated by applications in neuron science, are natural generalizations of the β-model to weighted graphs. Similar to the β-model, each vertex in maximum entropy models is assigned a potential parameter, and the degree sequence is the natural sufficient statistic....

In the PV system with storage batteries, as a maximum power point tracking (MPPT) device is used to enhance battery charging, the enhancement must be greater than the internal loss of the device itself, or there will be no net gain at all. To evaluate the MPPT device benefits under different...

Supersaturated designs have become increasingly popular in recent years because of their potential in saving run size and the technical novelty. In this paper, the minimum generalized aberration (MGA) criterion proposed by Ma and Fang (2001) (and another two equivalent criteria proposed by Xu...

The rapid growth of student loan debt has led to increased public attention on college students' financial aid and financial behaviour. This study addresses the psychological process underlying effective college student financial behaviour and its determinants. A model modified based on planned...

A new lower bound of the centered L2-discrepancy for four-level U-type designs is obtained. Our new lower bound is sharper and valid for a lot of designs more than other existing lower bound, which is a useful complement to the lower bounds of discrepancies.
