Testing goodness-of-fit of parametric spatial Trends
(M D P I AG, 2018-09-17)
[Abstract] The aim of this work is to propose and analyze the behavior of a test statistic to assess a parametric trend surface, that is, a regression model with spatially correlated errors. The asymptotic behavior under ...

[Abstract] There exist many different methods to choose the bandwidth in kernel regression. If, however, the target is regression based prediction for samples or populations with potentially different distributions, then ...
Cooperation on capacitated inventory situations with fixed holding costs
(Elsevier, 2015-03-16)
[Abstract] In this paper we analyze a situation in which several firms deal with inventory problems concerning the same type of product. We consider that each firm uses its limited capacity warehouse for storing purposes ...
Nonparametric estimation of the conditional variance function with correlated errors
(Taylor & Francis, 2006)
Nonparametric forecasting in time series: a comparative study
(Taylor & Francis, 2007)
The problem of predicting a future value of a time series is considered in this
paper. If the series follows a stationary Markov process, this can be done
by nonparametric estimation of the autoregression function. Two ...
