Simple additive weighting is a well-known method for scoring and ranking alternative options based on multiple attributes. However the pitfalls associated with this approach are not widely appreciated. For example, the apparently innocuous step of normalizing the various attribute data in order to obtain comparable figures leads to markedly different rankings depending on which normalization is...

Videogames now enable players to spend virtual fortunes on exotic virtual goods and even create and sell virtual artefacts. Online consumers may also browse endlessly through virtual marketplaces and create and display virtual goods. These virtual commodities are desired and enjoyed as if they were real, but are not actually bought, or owned in a material sense – often resulting in frustration ...

The common egg shell, Ovula ovum, is found in shallow reefs (down to 20 m) throughout the IndoPacific. It belongs to the family Ovulidae and is closely related to the true cowries of the family Cypraeidae (Abbott and Dance 2000). O. ovum are very common in the Marshall Islands especially around Majuro atoll where the local people collect them extensively. The shiny white shells are sold alone o...

We introduce a new interpretation of two re­ lated notions conditional utility and utility independence. Unlike the traditional inter­ pretation, the new interpretation render the notions the direct analogues of their prob­ abilistic counterparts. To capture these no­ tions formally, we appeal to the notion of util­ ity distribution, introduced in previous paper. We show that utility distributi...

We propose the group knockoff filter, a method for false discovery rate control in a linear regression setting where the features are grouped, and we would like to select a set of relevant groups which have a nonzero effect on the response. By considering the set of true and false discoveries at the group level, this method gains power relative to sparse regression methods. We also apply our me...

In this paper we consider the classical problem of dividing a land among many agents so that everybody is satisfied with the parcel she receives. In the literature, it is usually assumed that all the agents are endowed with cardinally comparable, additive, and monotone utility functions. In many economic and political situations violations of these assumptions may arise. We show how a family of...
