WebDensity Estimation in Higher Dimensions Kernel density estimation can in principle be used in any number of di-mensions. Usually a d-dimensional kernel K d of the product form K d(u)= d Õ i=1 K 1(u i) is used. The kernel density estimate is then bf n(x)= 1 ndet(H) n å i=1 K(H 1(x x i)) for some matrix H. Suppose H = hA where det(A) = 1. The ... WebJul 8, 2011 · The kernel density estimator has a parameter (called the bandwidth) that determines the size of the neighborhood used in the computation to compute the estimate. Small values of the bandwidth result in wavy, wiggly, KDEs, whereas large values result in smooth KDEs. The UNIVARIATE procedure has various methods to select the …
