An individual is asked to assess a real-valued variable y based on certain characteristics x=(x1 ,..., xm ), and on a database consisting of n observations of (x1 ,..., xm , y). A...
A possible approach to bandwidth selection for difference-based variance estimators in the nonparametric regression is proposed. The approach is based on the crossvalidation-type ...
A conjecture of G. Fan and A. Raspaud asserts that every bridgeless cubic graph contains three perfect matchings with empty intersection. We suggest a possible approach to problem...
