The Center for Causal Discovery has released the newest version of its causal discovery software, Tetrad (Version 6.4) and causal command command-line program (Version 0.3).  The focus on this release for Tetrad has been adding additional algorithms, an algorithm chooser, bootstrap for estimating edge probabilities to all algorithms.  There are also many many bug fixes.

 

These new versions are available from https://www.ccd.pitt.edu/tools/
