Setting Confidence Bounds

You can plot the confidence bounds around a metric by choosing Plot > Confidence Bounds > Show Confidence Bounds.

You can remove confidence bounds from your plot by choosing Plot > Confidence Bounds > Hide Confidence Bounds.

The Confidence Bounds Setup window includes the following options:

Sides allows you to specify which lines will be displayed on the plot.
- If you select None, confidence bounds will not be displayed on the plot.
- 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.
- Function (Type II) displays the confidence bounds on:
- - Reliability for Reliability vs. Time plots. This applies to discrete data types only.
  - Unreliability for Probability plots and Unreliability vs. Time plots. This applies to discrete data types only.
- Both displays both types.

Bounds On allows you to select whether you want to see confidence bounds on other factors, such as the growth potential, project value. the instantaneous line, the cumulative line or any combination of factors. This option is available only for certain plot types when using the Crow Extended analysis with the exact options available depending on the plot.
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.
