Optimal design for the Bradley-Terry paired comparison model
Abstract Paired comparisons are a popular tool for questionnaires in psychological marketing research. The quality of the statistical analysis of the responses heavily depends on the design, i.e. the choice of the alternatives in the comparisons. In this paper we show that the structure of locally optimal designs changes substantially with the parameters in the underlying utility. This fact is ...
متن کاملComparative Analysis of Bradley-Terry and Thurstone-Mosteller Paired Comparison Models for Image Quality Assessment
In image quality assessment, preference for various image processing algorithms or treatments is often determined using paired comparisons. In this experimental design, pairs of images processed by different algorithms or “treatments” are presented to a judge. The preferred treatment is selected and a tally is kept of the number of times each treatment is preferred to another. It is possible to...
متن کاملComparing the Efficiency of Dmus with Normal and Skew-Normal Distribution using Data Envelopment Analysis
Data envelopment analysis (DEA) is a nonparametric approach to evaluate theefficiency of decision making units (DMU) using mathematical programmingtechniques. Almost, all of the previous researches in stochastic DEA have been usedthe stochastic data when the inputs and outputs are normally distributed. But, thisassumption may not be true in practice. Therefore, using a normal distribution wi...
متن کاملFitting loglinear Bradley-Terry models (LLBT) for paired comparisons using the R package prefmod
This paper aims at introducing the R package prefmod (Hatzinger, 2009) which allows the user to fit various models to paired comparison data. These models give estimated overall rankings of objects or items where each subject (respondent/judge) makes one or more comparisons between pairs of objects (items). The focus is on the loglinear Bradley-Terry (LLBT) model, the loglinear formulation of t...
متن کاملBayesian Inference of Log-linear Version of the Bradley-Terry Model for Paired Comparisons Using Uninformative Prior
Bayesian analysis of log-linear version of the Bradley-Terry[3] model is performed in this paper considering generalization of Dittrich et al.,[6]; Dittrich et al.,[7] and the Dittrich et al.,[8] to modify and re-estimate the model parameters to overcome a small deficiency in the estimation of a single log odd parameter being aliased. To ensure ranking is maintained, we computed the posterior p...
