[3.05] Correlation With Errors-in-Variables and an Application to Galaxies

W. H. Jefferys (University of Texas)

The usual theory of correlation coefficients fails when one or both of the observed quantities has error. I describe a Bayesian approach that correctly handles this errors-in-variables problem, and which also gives posterior odds on the model with correlation against the model without correlation, allowing a decision as to whether the correlation should be considered real or not.
