Petros Hadjicostas, assistant professor in the UNLV Department of Mathematical Sciences, will be the featured speaker at an upcoming Department of Mathematical Sciences statistics seminar. His talk is titled, "Right-Invariant Generalized Metrics Applied to Rank Correlation Coefficients."

In this talk, we investigate properties of rank correlation coefficients that can be derived from right-invariant generalized metrics on the symmetric group. We present some new inequalities involving different generalized metrics. If there is time available, using the Hausdorff generalized metric, we may show how to construct circular rank correlation coefficients from regular rank correlation coefficients.
