DOI: 10.1007/s11222-025-10744-1
Abstract: We devise a new formula for measuring the effective degrees of freedom (EDoF) in kernel density estimation (KDE). Starting from the orthogonal polynomial sequence (OPS) expansion for the ratio of the empirical to the oracle… read more here.

DOI: 10.1080/01621459.2019.1604363
Abstract: Abstract Model averaging generally provides better predictions than model selection, but the existing model averaging methods cannot lead to parsimonious models. Parsimony is an especially important property when the number of parameters is large. To… read more here.

DOI: 10.2166/hydro.2017.116
Abstract: The numerical and analytical models used for transient simulations, and hence for the pressurized pipe system diagnosis, require the definition of a rheological component related to the pipe material. The introduction and the following widespread… read more here.
