Exploring Conceptual Differences Among Nonparametric Estimators of Treatment Heterogeneity in the Context of Clustered Data
One aim of educational research is to evaluate interventions developed to improve student learning and behavioral outcomes. Estimating an...

Measures of interrater agreement for quantitative data
In this paper measures of interrater absolute agreement for quantitative measurements based on the standard deviation are proposed. Such indices...

D-optimal designs for hierarchical linear models with intraclass covariance structure
Intraclass correlation, used for measuring the degree of intrafamily resemblance, arises typically in psychology, education and genetics. In this...

Introduction
Chapter 1 provides an introduction to the structure of the book, which more or less follows the order of...

Measures of Fourfold Association II
Chapter 14 is the second of two chapters describing connections, equivalencies, and relationships relating to...
-
A Comparison of Reliability Coefficients for Ordinal Rating Scales
Kappa coefficients are commonly used for quantifying reliability on a categorical scale, whereas correlation coefficients are commonly applied to...

Estimators of various kappa coefficients based on the unbiased estimator of the expected index of agreements
To measure the degree of agreement between R observers who independently classify n subjects within K categories, various kappa -type coefficients are...
-
Descriptive Analyses of Interrater Agreement for Ordinal Rating Scales
A measure of interrater absolute agreement for ordinal rating scales that have advantages respect to intraclass correlation coefficients and other...

PC priors for residual correlation parameters in one-factor mixed models
Lack of independence in the residuals from linear regression motivates the use of random effect models in many applied fields. We start from the...

If the tools to gather information affect data quality: violence against women survey case
National victimization surveys, and among them women's safety surveys, are recognized as an important tool for gaining insight into many aspects of...

Testing covariance structures belonging to a quadratic subspace under a doubly multivariate model
A hypothesis related to the block structure of a covariance matrix under the doubly multivariate normal model is studied. It is assumed that the...

Sample Size Calculations
In this chapter several sample size calculation formulas are introduced. They include the standard sample size calculation formula for both...

Comparing Hyperprior Distributions to Estimate Variance Components for Interrater Reliability Coefficients
Interrater reliability (IRR) is often estimated by intraclass correlation coefficients (ICCs). Using Markov chain Monte Carlo (MCMC) estimation of...

Mixture polarization in inter-rater agreement analysis: a Bayesian nonparametric index
In several observational contexts where different raters evaluate a set of items, it is common to assume that all raters draw their scores from the...

Systematic Sampling
In this sampling method, the first unit is selected by using a random number and the rest of the units are selected by a predetermined pattern. This...
