Relevant Information:
This dataset was assembled by analyzing the publicly-available CVS archives of the Nickle programming language (http://nickle.org) using a modified version of CVSAnalY (http://metricsgrimoire.github.io/CVSAnalY). It is intended for a wide variety of uses, and thus no dependent variable is specified. See Massey's PROMISE 2005 paper, "Longitudinal Analysis of Long-Timescale Open Source Repository Data", for further information.
