Two-Monitor Statistics Report

A two-monitor statistics report allows you to compute the covariance or correlation of two monitors.

The two-monitor statistics report value is determined by whatever data you have in your sample set at whatever iteration (or time step) you are on.

For details on setting up a two-monitor statistics report and the results, see Obtaining Statistics from Data in Monitors.

Two-Monitor Statistics Report Properties

Units
Set automatically based on the units used by the base report.
Statistic
Selects a type of computation:
  • Covariance
  • Correlation
Sample collection policy
Specifies whether the report is computed from all samples or the last N samples, where N is specified in the Last N Samples child node. The default is All samples.
Monitor 1
Selects the monitor of the first base report from which from to obtain data.
Monitor 2
Selects the monitor of the second base report from which from to obtain data.

Child Node Properties

The two-monitor statistics report node has a child node named either All samples or Last N Samples, depending on the selection made under Sample collection policy.

Sample count
The number of data samples N collected for each cell within the monitor. For the Last N Samples node only. For multiple inputs, the report collects enough samples from the input monitors so that there are N iterations in common across all of them. The report then runs on these N common iterations.
Sample start event
The event at which to begin collection data. See User-Defined Update Events.
Include start event sample
When On, includes the sample at a start event in the sample collection.
