Quantifying the degree of spatial dependence for linguistic variables is a key task for analyzing dialectal variation. However, existing approaches have important drawbacks. First, they are based on parametric models of dependence, which limits their power in cases where the underlying parametric assumptions are violated. Second, they are not applicable to all types of linguistic data: some approaches apply only to frequencies, others to boolean indicators of whether a linguistic variable is present.

In this talk, I will present a new approach for measuring geographical language variation, which solves both of these problems. The approach builds on Reproducing Kernel Hilbert space (RKHS) representations for nonparametric statistics. I will discuss experiments on both synthetic data and a diverse set of empirical datasets.
