Setting Confidence Bounds

You can include and specify the confidence bounds on plots associated with standard folios, degradation folios, warranty analysis folios and parametric RDA folios by choosing Plot > Confidence Bounds > Confidence Bounds.

The Confidence Bounds Setup window will appear, allowing you to define the properties of the confidence bounds lines to be displayed on the plot.

Note: Confidence bounds are not available if the data type is free-form data.

• Sides allows you to specify which lines will be displayed on the plot.

• • None if selected, confidence bounds will not be displayed on the plot.

Note that you can also remove confidence bounds from your plot by choosing Plot > Confidence Bounds > Hide Confidence Bounds.

• • Two-Sided displays two-sided confidence bounds on the plot.

  • One-Sided displays one-sided confidence bounds on the plot. You can select one type or both types.

  • • Show Top displays the top line for one-sided confidence bounds on the plot.

    • Show Bottom displays the bottom line for one-sided confidence bounds on the plot.

• Type allows you to specify which types of confidence bounds you want displayed on the plot. You can select one type or both types. Note that not all options are available with every plot.

• • Time (Type I) displays the confidence bounds on time.

  • Reliability (Type II) displays the confidence bounds on:

  • • Reliability for Reliability vs. Time plots

    • Unreliability for Probability plots and Unreliability vs. Time plots

• • Both displays both types.

• Bounds On  

This option is available only for the life vs. stress plot type. It allows you to select to display confidence bounds on the scale parameter, mean line or both.

• Confidence Level % allows you to set the percentage for the confidence bounds.

• Resolution allows you to specify the resolution of the confidence bounds lines on the plot by dragging the slider or, for fine adjustments, clicking the slider and then using the arrow keys. The number of points plotted to create the lines is displayed beside the field name.
