A grammar of model analysis

Project description

py_grama

Documentation Status Build Status codecov

Implementation of a grammar of model analysis (grama). See the documentation for more info.

Overview

Grama is a grammar of model analysis---a domain-specific language embedded in Python that supports building and analyzing models with quantified uncertainties. This language is heavily inspired by the Tidyverse. Grama provides convenient syntax for building a model (with functions and distributions), generating data, and visualizing results. The purpose of this language is to support scientists and engineers learning to handle uncertainty, and to improve documentation + reproducibility of results.

Installation

For a manual install clone this repo, change directories and run the following to install dependencies. (Note: I recommend Anaconda as a Python distribution; it takes care of most of the dependencies.)

$ git clone git@github.com:zdelrosario/py_grama.git
$ cd py_grama/
$ pip install -r requirements.txt
$ pip install .
# Check install
$ python
> import grama
