Estimation of a relative risk function using a ratio of two kernel density estimates is considered, concentrating on the problem of choosing the smoothing parameters. A cross-validation method is ...

A distribution-free imputation procedure based on nonparametric kernel regression is proposed to estimate the distribution function and quantiles of a random variable that is incompletely observed.

Tracking human behavioral patterns in cities can be used to determine urban delineations and urban land use, which has the potential to improve urban planning.
