Heterogeneity Measures in Customer Satisfaction Analysis

Journal of Classification, 2011
In this paper we deal with the problem of identifying a valid way to characterize heterogeneity in the analysis of customer satisfaction observing the phenomenon through a new perspective. In the literature, the variability of a Customer Satisfaction index is measured by the standard deviation or the coefficient of variation. In this way, heterogeneity

Heterogeneous Treatment Effect Analysis [PDF]

, 2010
Methods for causal inference and the estimation of treatment effects have received much attention in recent years. Most of the methodological and applied work focuses on the identification of so-called average treatment effects, possibly restricted to the treated or the untreated. However, treatment effects may vary (hence the averaging), and it can be

Approaches to heterogeneity in meta‐analysis

Statistics in Medicine, 2001
AbstractThis paper reviews publications from January 1999 to March 2001 on reproductive health topics that were self‐identified as meta‐analysis or were indexed as meta‐analysis in MEDLINE. It sought to assess whether tests of statistical heterogeneity were done, whether the results were reported, and how a finding of significance for a test of ...

Experimental Analysis of Heterogeneous Wireless Networks

2004
Packet loss and delay in Internet degrade the quality of requested services like VoIP (Voice over IP) or Video Streaming. In novel network scenarios where wired and wireless connections are melted together, a real measure of these parameters is fundamental in a planning process of new services over novel network infrastructures.

Meta-analysis of heterogeneity

2021
Meta-analyses Applying a Food and Drug Administration (FDA) method for opioid measurement dilemmas, we used meta-analytic techniques to quantify how much heterogeneity would have been observed across hypothetical state-comparison studies, each applying one of the 4 variants on the same sample (fixed effects). In preliminary analyses, Florida generally

Heterogeneous and Homogeneous Immunoassays for Drug Analysis

Bioanalysis, 2014
Immunoassays are very useful techniques to perform screening and semi-quantitative analysis of hundreds of different xenobiotics. Small sample volumes are required and pretreatment is usually unnecessary (e.g., homogeneous immunoassays). Fully automated and high-throughput systems are available, which help physicians to take timely decisions.
