FC {ThurMod}

Paired comparisons of $N=15$ items from one factor/trait (Thurstonian modeling)

Description

This data set contains synthetic data of 1000 participants on all binary indicators of 15 items. For each paired comparison, participants had to rank the two alternative items according to their preference. It is assumed that transitivity holds (that is, the data comes from a ranking task). More details can be found in Brown and Maydeu-Olivares (2011), Jansen and Schulze (2023) and Maydeu-Olivares and Böckenholt (2005).

Usage

Format

A data frame with 1000 observations on 105 variables. For a variable ixiy, the result is the response preferences between item x and item y. It is coded a 1, if item x is preferred over item y, and 0 otherwise.
