This paper reviews the main problems that have to be faced when taking a multidimensional approach to poverty and gives a survey of the solutions that have hitherto been proposed to solve these problems. The paper starts with a quick summary of the cardinal approach to uni-dimensional poverty...

Polytomous Item Response Theory Models provides a unified, comprehensive introduction to the range of polytomous models available within item response theory (IRT). It begins by outlining the primary structural distinction between the two major types of polytomous IRT models. This focuses on the...

Multiple choice items on tests and Likert items on surveys are ubiquitous in educational, social and behavioral science research; however, methods for analyzing of such data can be problematic. Multidimensional item response theory models are proposed that yield structured Poisson regression...
