In this paper we describe a computer intensive method to find the ridge parameter in a prediction oriented linear model. With the help of a factorial experimental design the method is tested and compared to a classical one.

The present study explores the differential effects of having a National/Regional celebrity in an advertisement/ endorsement. More specifically the study intends to find out whether a National celebrity would have a more favorable impact on consumer attitudes than a Regional celebrity when...

In-group favouritism behaviour is observed everywhere around the world and previous research has shown that this behaviour is also easily triggered in a laboratory in various contexts. However, little is known about why different magnitudes of in-group favouritism are observed across societies....

This work aimed to characterize and optimize the variables that influence membrane electrode preparation using a design of experiment (DOE) approach in two steps. First, in the process of electrode preparation, the quantity of PTFE and drying time were found to have no significant influence...

This paper reviews the state of the art in five related types of analysis, namely (i) sensitivity or what-if analysis, (ii) uncertainty or risk analysis, (iii) screening, (iv) validation, and (v) optimization. The main question is: when should which type of analysis be applied; which statistical...

We experimentally investigate the development of voluntary transfers in an overlapping generations environment. By varying the information conditions of the game, we study whether the development of transfers is related to the possibility of future generations to monitor and reciprocate...
