From the PARcore Data Visualization Studio Landing Page, navigate to this report by selecting the Conditional Expectations and Variances icon.

This report is only applicable for requests that include the Analysis Type of Item Response Theory with Produce Calibration selected and have the Data Specification option "Use Predictor Vectors for Concurrent Calibrations" toggled to "Yes".  If the predictor vectors option is "No" this report will not appear on the landing page and will not be produced.


The bento box menu icon at the top left of the report can be used to navigate back to the Landing Page.

Refer to Visualize Results for general information about filter navigation for any report.  The filter for this report is:
     

  • Analysis - select one analysis sequence number to view at a time.  The analysis sequence number will reflect the sequencing from Request Details for this request.  The analysis template name used for this request will also be included in the filter description.
    • Upon first initializing this dashboard, the filter will display as (Choose your analysis) and a selection must be made. 
      • Select the search icon (magnifying glass) and enter search text to see Analysis filter options for the request you are viewing. 
      • Using an asterisk in the search text box will display all possible analyses to choose from.  
    • Once the current analysis results have been reviewed, continue to use the search feature or utilize the slider arrows (< and >) to view each analysis one at a time.  If there is only one analysis for this report the navigation buttons will be disabled.

                

Conditional Expectations and Variances of Underlying Latent Vectors Given Predictors
  • When producing concurrent calibration with predictor vectors, summary statistics are displayed for your selected analysis:  ID, Mean, and Covariance.   
  • Rows are ordered by alphabetical ID (form).


 
Additional statistics are produced and available to users beyond what is presented in the Data Visualization Studio.  Refer to the RTSSTAT API and Download Statistics help documentation for more information regarding accessing all of the available statistics produced.
