This paper discusses the representability of discrete logit-type models including multinomial logit and nested logit model from a mathematical approach. It is shown that the logit-type models can be reconstructed from mathematical approximation theory with sigmoidal functions widely used in Neural Network modeling without the basic assumptions such as IIA and iid, and the distribution (or densi...

Several studies have shown that as many as 20% of European schooled adolescents report self-destructive thoughts/behaviours. Using multinomial logistic regression analysis, the present study investigated the family and individual variables that predict reports of these behaviours. Three groups, one without reports of self-destructive thoughts/behaviours (NSDTB; n= 998), one with reports of self...

Abstract The objective of this chapter is to provide practical guidelines for implementing various logistic-oriented applications. In particular, part starts with a crucial point pertaining access control using KIS.Devices and external RFID readers. Subsequently, an application concerning monitoring product levels in small warehouse proposed. remaining three sections deal transportation systems...
