This is a replication package with data used in a study by T. Alkhaeir and B. Walter "The effect of code smells and design patterns on two change-related metrics: An exploratory study" This dataset contains the following folders: Aggregated Results Per System  For each subject system (AOI, Jedit, JHotDraw), we identify the following datasets: DP, nDP, S, nS ,SDP, nSDP, SnDP, and nSnDP. Each dataset is represented by a separate csv file.  Those csv files include raw data about every class in every release, the csv files also include columns which represent: - CHURN (CLPLPR(C)100): defined as the sum of added and deleted lines in a class in a release, adjusted to the size of the class and to the number of revisions in the release; - and FREQ (MTPR(C)100): defined as the average number of changes made to a class in a release, adjusted to the number of revisions in the release Detailed Results Per Smell Or Pattern  For each specific code smell (S) in each public release (Rel) of all subject systems, we identify SDP and SnDP datasets. Each dataset is in a separate .csv file  For each specific design pattern (DP) in each public release (Rel) of all subject systems, we identify SDP and nSDP  Plots We also include QQ plots for CHURN, FREQ values for every dataset in every system, that could serve as a supplementary data for the paper.
