1) New module on our on-line course: Module 9: Single-level and multilevel models for ordinal responses. In Module 6 we saw how multiple regression models for continuous responses can be generalised to handle binary responses, and in Module 7 these models were further extended for the analysis of binary data with a two-level hierarchical structure. This module considers standard (single-level) and multilevel models for ordinal categorical response variables, where the numeric codes assigned to categories imply some ordering. We begin with a description of two approaches for the analysis of single-level ordinal data: a) the cumulative logit model which is appropriate for variables such as Likert scale items, where respondents are asked to indicate their strength of agreement with a statement from 'strongly agree' to 'strongly disagree', and educational tests where marks are available as grades rather than percentage scores; and b) the continuation ratio model for ordinal responses that can be viewed as the result of a series of sequential decisions or actions (e.g. highest level of educational qualifications). We then show how the cumulative logit model can be extended for the analysis of data with a two-level hierarchical structure.

This takes place on 12-13 December 2011 in the Hong Kong Theatre, Clement House, London School of Economics. The registration fee of £75 for the two days includes a buffet and a sandwich lunch.
