Prest

Build Status

Revealed-preference analysis and preference estimation from choice data: https://prestsoftware.com

Introduction

Prest is a free and user-friendly desktop application for computational revealed preference analysis. It allows for processing choice datasets that economists, psychologists and consumer/marketing researchers often generate through experiments, market studies or surveys.

Documentation and downloads

Pre-built Prest binaries can be downloaded from the landing page of the documentation at https://prestsoftware.com.

Building and running Prest

Dependencies:

  • Rust 1.26 stable + Cargo
  • Python 3 (we use 3.6 and 3.7) + pip

Install the dependencies, compile everything and run:

$ pip install --user -r gui/requirements.txt
$ make run

Optionally, work in a virtual environment:

$ python3 -m venv prest.env
$ source prest.env/bin/activate
# The next line is different from the previous installation command.
$ pip install -r gui/requirements.txt
$ make run

The build invoked by the commands above will, among other things, build the HTML documentation, which is required for the help features of Prest. It will also typecheck the code using mypy.

Testing

$ make test      # quick test during development
$ make fulltest  # includes long-running tests

The most comprehensive test is the integration test, which runs the whole pipeline including the Rust core on the example datasets. It is invoked in the course of the above commands; make test uses only the small example datasets, while make fulltest uses all of them.

Packaging

We build stand-alone binaries using PyInstaller. These build scripts are not published at the moment.
