tab and click the OK button in the Weibull & Reliability/Failure Time Analysis dialog box to display the Weibull Analysis: Results (Grouped Data) dialog box, which contains three tabs: Quick, Estimate, and Reliability. Note that similar procedures for grouped data (life tables) are available in the Survival Analysis module.Summary box
The Summary box at the top of the dialog box displays a summary of the parameters established so far in the analysis.
Copy button. Click the Copy button to copy either the selected text (if text has been selected) in the Summary box or all of the text (if no text has been selected) to the Clipboard. Note that the copied text retains formatting information (such as font, color, etc.).


Summary
Click the
Summary button to produce a spreadsheet with the current parameter values. If the current parameter values are the maximum likelihood estimates (as estimated when the
ML shape and scale parameters option button is selected in the Estimate parameters (weighted least squares) group box on the
Estimate
tab), the spreadsheet will also contain the standard errors and confidence intervals for the parameter estimates. Note that the confidence intervals are adjusted to reflect the fact that the valid parameter space is bounded (i.e., the shape parameter must be greater than 0). See Nelson (1990; Section 5.7) or Dodson (1994) for computational details.Cancel
