Introduction
------------

Prest is an open-source and user-friendly **Windows & macOS desktop application**.

It can be used to analyze choice datasets created by economists, psychologists and marketing researchers. 

Its key novelties pertain to general datasets where choice alternatives are discrete. 

Prest allows for estimating non-parametrically the decision maker's preferences from such general datasets.

It does so by finding out how "close" the observed choices are to being explainable by **rational choice or some model of bounded-rational choice**.

In this way, Prest recovers both the individual's **decision rule** and their **preferences conditional on that rule**.
