The distribution of the number of bidders in auctions with uncertain numbers is usually assumed to be Poisson. The observed distribution, for example in OCS Federal Offshore Oil Lease Sales, is apparently not Poisson. A simple model is presented showing that if the objects have different values...

This paper is designed to show how a typical sequential probabilistic model may be formulated in linear programming terms. In contrast with Dantzig and Radner, the time horizon here is an infinite one. For another very closely related study, the reader is referred to a paper by R. Howard. The...

A recent mathematical model by Horvath which predicts the process of participation in group discussions is compared to several alternative models. The models can be applied to data for which the basic unit is the act and to data for which the basic unit is a continuous sequence of acts. In both...
