Modify the Confidence Level for a Probability Distribution Analysis

The Confidence Level specifies how the optimistic and realistic scenarios will be selected in a Monte Carlo Simulation for TTR Distributions in an analysis. The Confidence Level indicates whether the distribution is within the confidence limits or not. The default Confidence Level for an analysis is 90 percent.

You can modify the Confidence Level from the Analysis Summary workspace or from any of the plot tabs in the left pane.

Steps

Access a Probability Distribution Analysis for which you want to modify the Confidence Level.
If you want to change the Confidence Level from the Analysis Summary workspace:
1. In the bottom section, select Distribution Options, and then select .
  
  The Confidence Level field is enabled.
  
  Note: If the Confidence Level field is disabled, select the Use Confidence check box to activate the confidence level and enable the Confidence Level field.
2. In the Confidence Level box, select the desired Confidence Level, and then select .
  
  The GE Digital APM system displays the confidence intervals for the analysis based on the percentage you entered in the Confidence Level field.

If you want to change the Confidence Level from one of the plot tabs (e.g., Probability Plot tab):
1. In the left pane, select the Probability Plot tab.
  
  The Probability Plot appears in the workspace.
  
  Note: You can also change the Confidence Level via the PDF Plot or CDF Plot tabs.
2. In the upper-right corner of the workspace, select Distribution Options, and then select Fit Method.
  
  The Select Confidence Level window appears.
3. Select the desired Confidence Level, and then select OK.
  
  The GE Digital APM system displays the confidence intervals for the analysis based on the percentage you entered in the Confidence Level field.
