To add a Weibull++ life data folio to a project, choose Home > Insert > Life Data or right-click the Life Data folder in the current project explorer and choose Add Life Data on the shortcut menu.
A setup window will prompt you to select a data type to use in the folio and a unit appropriate for your data (the unit may be measured in mileage, distance, weight, etc.; see Unit Settings).
There are two types of data available: times-to-failure data or free-form data. In addition, times-to-failure data may contain three forms of censoring: suspensions (right censored), interval censored or left censored data. (See Weibull++ Data Types.)
Any of the times-to-failure data types can also be entered as grouped data. The ReliaWiki resources portal has more information on grouped data analysis at: http://www.reliawiki.org/index.php/Grouped_Data_Parameter_Estimation.
The data type you select determines the data entry columns that will appear in the data sheet. When you select a data option, the preview area at the bottom of the setup window shows you the names of the data entry columns that will appear in the data sheet, as shown in the following example.
