Non-Parametric LDA Tab

The Non-Parametric LDA tab is visible when you view a non-parametric life data analysis (LDA) folio data sheet.

Analysis

Calculate obtains the reliability estimates based on the chosen non-parametric method. It then converts the results to free-form data and performs a parametric analysis based on the chosen life distribution.

Plot creates a Reliability vs. Time plot of the non-parametric analysis. The scaling, setup, exporting and other features are similar to the options available for other Weibull++ plot sheets. Features that are not applicable to this plot will be hidden or disabled.

Quick Calculation Pad opens the Quick Calculation Pad, which allows you to calculate results such as mean life and probability of failure based on the results of the standard life data analysis. It uses the same calculations that you can perform in a Weibull++ standard folio QCP.

Distribution Wizard opens the Distribution Wizard, which helps you select the distribution that best fits the data set based on the chosen parameter estimation method (i.e., RRX or RRY). In the non-parametric LDA folio, the ranking in the Distribution Wizard is based on the life data model.

Transfer Life Data

Transfer Life Data to New Folio allows you to transfer the values from the Life Data Model area of the control panel to a fee-form data sheet in a new Weibull++ standard folio. The selected failure time values (start time, end time or average time) will be copied to the “X-Axis value” column, and the reliability values will be converted to their inverse values (i.e., unreliability) and then transferred to the “Y-Axis value” column.

Transfer Life Data to Selected Folio allows you to transfer the values from the Life Data Model area of the control panel to a free-form data sheet in an existing Weibull++ standard folio.

Synthesis

Publish Model allows you to use the life data model (i.e., life distribution and parameter estimates) as a resource object and make it available for unlimited use anywhere within the project, in any Synthesis-enabled application that has a need for that type of object.
