Data Sets
My early studies of decisions from experience, like most other studies at the time, focused on small samples of subjects.
For example, in Bereby-Meyer and Erev (1998) we run only 14 participants in each of the three experimental conditions. The common assumption was that since each participant makes many decisions (500 in that study), the data is large enough.
Later we realized that the many participants tend to select their favorite action after several trials, and repeat this choice in most other trials. Thus, it is easy to overfit these data sets. To address this difficulty, my recent research focuses on large data sets, and choice prediction competitions.
Below are links to some of these data sets and the papers that summarize them.
