Statistical Methodology

by William B. Simpson


William Simpson is developing methods of inference to use when assumptions of standard models are not met. He has created a hypothesis test to use for ipsative variables that adjusts for the non-zero correlations among variables expected under the null hypothesis. He has developed a number of extensions of the quadratic assignment procedure -- a method used for dyadic data in social network analysis -- for generalized linear models, multiple networks, and network panel data.
