Ordinal Item Response Theory Models for the Evaluation of Heterogeneity in Attitudes. Mauerer, Ingrid Doris Tutz, Gerhard Opinión pública Sociología electoral Estadística Copyright de los autores The contribution provides ordinal item response models to investigate heterogeneity in attitudes. In contrast to standard models, the approach accounts for covariate effects in studying two essential components of attitudes: direction and strength.
