Presentation Topic: Dialect Survey Maps (A visualization)
They examined regional dialect variation in the United States. Each observation can be thought of as a realization of a categorical random variable with a particular parameter vector that is a function of location—their goal was to interpolate among these points in order to estimate these parameter vectors at a given location, making use of a combination of kernel density estimation and non-parametric smoothing techniques. Results in a smooth field of parameter estimates over the prediction region. Using these results, a method for mapping aggregate dialect distance was developed.
