Performance Sampling and Multiple Choices: Brownian Motion Models.

This paper extends the Brownian motion model for a decision making process that was developed in (Romanow, 1984). Several of the assumptions of the basic model are relaxed here. It is no longer assumed that performance is always observed, but rather that observation is intermittent. Models are developed for several different data collection schemes. The original model allowed two choice alternatives. Here, a third choice is included by considering a model in which a Brownian motion may cross either of two mutually exclusive boundaries.
