Weibull Parameters
The window beneath the LDA Navigator contains a number of tabbed panes, depending on the selected analysis type.
• When Life Data is selected, this window contains either two or three panes: Parameters, Advanced (when applicable), and Plot Options.
• When Warranty Analysis is selected, the previous three panes are available as well two additional panes: Warranty and Forecast Parameters.
• When Degradation Analysis is selected, only two panes are available: Parameters and Plot Options.
The two panes common to all life data sets display analysis parameters and plot options.
• Parameters — Specifies parameters for analyzing the selected data set.
• Plot Options — Specifies the number and type of plots to display in the Weibull Plot pane in the window on the right.
When the Advanced pane is applicable, it specifies the estimation method and any needed distribution parameters.
When a life data set is calculated, results display at the bottom of panes in which you enter parameter, in the Calculation results area. Here, you can specify a fixed value for a particular calculated value if you want. The results shown depend on the distribution selected.
All panes in the lower right window display toolbar buttons on the right side of the title bar. Buttons are available only when they are applicable to the active data set.
You can click these toolbar buttons to perform common tasks, including:
• Calculating the active data set
• Showing the plot for the active data set
• Opening the Summary Calculator window to perform additional calculations
• Running best fit distribution analysis
