AAPC Segment Ranges

From the AAPC Segment Ranges section, you can select to display the AAPC for the entire range of data, the last N observations, or other specified ranges.

The AAPC Confidence Intervals can be calculated using the Parametric option or the Empirical Quantile option.

 

When the AAPC Confidence Intervals Parametric Method option is selected, the AAPCs can be computed after the Joinpoint calculations are performed, using the APCs. With this option, the AAPCs can be modified in the output by following the following procedure, without having to rerun the session.

  1. When viewing the Joinpoint output, to specify which ranges to display use the Output > Specify AAPC Ranges... menu item from the top of the main Joinpoint Output window.

  2. From the Specify AAPC Ranges window, you can select to display the AAPC for the entire range of data, the last N observations, or other specified ranges.

 

When the AAPC Confidence Intervals Empirical Quantile option is selected, the AAPCs cannot be computed after the Joinpoint calculations are performed.

When the Exclude Data Points option is selected, the last "N" AAPC ranges may be affected.  For more information regarding this, please go to the Exclude Data Point help section.
