Ph.D. Student

In the Methodology and Statistics group of the Psychological Institute there is a vacancy (vacany number 10-138) for a:
Ph.D. Student on the subject ‘Multivariate logistics regression using the ideal point classification model’
Full time appointment, preferably between October 2010 and October 2014.

Project description
Multivariate categorical data, with multiple dependent variables and one or more independent variables are often collected in the social sciences. In the Netherlands study of depression and anxiety (NESDA, see, for example, data are collected on both depression and anxiety disorders (dependent variables) and personality characteristics (independent variables). For the analysis of such data, however, only limited statistical tools are available. The methodology that is currently available makes either unverifiable assumptions or requires the independent variables to be categorized. In this project new methodology is proposed, based on the ideal point classification model, which requires a minimal set of assumptions and takes the data as it is (no categorization required). Essential tools for the evaluation of effects and for the design of empirical studies will also be proposed.
A more detailed project description can be requested from Dr. Mark de Rooij ( and/or Jacqueline Vreriks (
