 The output_stats array controls the type of output that the Series-Analysis tool generates. Each flag corresponds to an output line type in the STAT file and is used to specify the comma-separated list of statistics to be computed. Use the column names from the tables listed below to specify the statistics. The output flags correspond to the following types of output line types:
