I study measurement error in survey questions. Currently I am pursuing my PhD at the IOPS, through Tilburg University, the Netherlands.

I live in Barcelona, where I work for the ESS.

Programs

D. L. Oberski (2010). "AutoMTMM"
A collection of scripts that extract the results from many LISREL MTMM analyses and store them in a relational database. Calculates standard errors and covariances of reliability and validity coefficients.
D. L. Oberski (2009). "Jrule for Mplus"
A power analysis program that operates on Mplus output. The GUI provides plots and advanced options for looking at possible misspecifications in the model.
D. L. Oberski, S. Kuipers and W. E. Saris (2007). "SQP: Survey Quality Predictor"
A program to code characteristics of survey questions and predict their reliability and internal validity from those characteristics.
