Description

This is a PROMISE Software Engineering Repository data set made publicly available in order to encourage repeatable, verifiable, refutable, and/or improvable predictive models of software engineering.

  1. Title: Nickle Repository Transaction Data

  2. Sources: (a) Original creators of database: Bart Massey 01 503 725-5393 Computer Science Dept. PO Box 751 MS CMPS Portland State University Portland, OR USA 97207-0751 bart@cs.pdx.edu

(c) Date received: 31 March 2005

  1. Past Usage: none

  2. 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.
