COMNET III Reports and Statistics Select the Axes tab, select the Scale sub-tab, and check all the Is Default boxes. Then select the Annotation sub-tab, click the three-dot button next to Annotation Method: Values, and check all the Is Default boxes there. See the ‘Comnet III Chart Controls’ help file for more information on manipulating the way charts are displayed. 1.1.3 Exporting Statistics Files The statistics monitors in COMNET III collect raw observation data as well as data sampled over a specified interval. All of the simulation statistics collected during the run (raw observational data and interval sampled data) can be exported. Use the Simulate/Run Parameters option to display the Run Parameters tabs. The Replications tab has a Number of replications field in which you can enter the number of times you wish your model to run. When multiple replications have been set, the desired 6
Statistics confidence interval alpha can be set under the Statistics tab. On the same tab, select the Export stats after run checkbox to automatically produce an export file of all statistics upon completing the simulation. Select Include percentiles in export if you wish percentiles to be included in the exported file. The export file can be imported directly into spreadsheet packages such as Microsoft Excel for further analysis. Turning on export statistics does nothing to identify what gets exported. Instead it exports what has been requested elsewhere. It exports all monitors that have been turned on explicitly via the Statistics requests. It exports all data that is requested from the report requests. The export file contains all the collected statistics in the model except for the actual observations that may be available for plotting. Once the simulation is completed, click on File/Export/Simulation Statistics and specify the file name to export to. The export file is an alternative to the report file and the report includes both monitor information and counter information. The file will have an extension of .xpt. The statistical information is exported in a tabular format. The first row of the file contains the model name and date of the simulation run. The second row contains the row titles for n following rows where n is the number of replications. These rows provide start and stop times for each replication. The interval sampled data is written to the fields that begin with Int., while the raw data is written to the other fields. Each line in the file has the following tab-delimited fields: Title Units Rep Min Max Mean Std Dev Sum Sum of Squares Count The replication number. When there is more than one replication, replication -1 combines statistics for all replications as though the simulation consisted of one long replication. Replication 0 treats each replication as one observation and provides the statistics based on these summary observations. The smallest observed value or level. The largest observed value or level. The mean observed value or level. The standard deviation of the observed values or levels. For delay types of performance measures, the sum of the delays. For level statistics (e.g., buffer usage), the levels are time-weighted. To compute the mean for a level statistic, divide the Sum by the length of a replication. For delay types of performance measures, the sum of the observed values squared. For level statistics, the levels are time-weighted. The number of observations. 7
