In this paper, the methods of time series for nonlinearity are briefly surveyed, with particular attention paid to a new test design based on a neural network specification. The proposed integrated expert system contains two main components: an identification environment and a robust forecasting...

Kernel-type estimators of the multivariate density of stationary random fields indexed by multidimensional lattice points space are investigated. Sufficient conditions for kernel estimators to converge uniformly are obtained. The estimators can attain the optimal rates L[infinity] of...

Purpose – The purpose of this paper is to investigate optimal decision methods under a cooperative situation in two-echelon logistic models. Design/methodology/approach – The authors propose the optimal strategies of exporters in the three types of rival game behaviors: Stackelberg,...

Purpose – The purpose of this paper is to use soft computing technique and fuzzy statistical tool to evaluate people's performance on the marketing research and time management. Design/methodology/approach – Through standardized measurement system, the authors come up with real-value data to...
