Alter Data Type Window

The Alter Data Type window is used to specify the type of life data response (e.g., right censored data) that is used in the current experiment. It is available only for designs that are configured to accept life data. To open the window, choose Data > Design > Alter Data Type or by click the icon on the Data tab control panel.

The following options are available in the Life Data Response Type area of the Alter Data Type window.

• Select My data contains units that did not fail (suspensions/right censored data) if the response data includes times at which some test units were observed as not being failed.
• Select My data set contains units with an uncertain failure time (interval/left censored data) if the response data includes intervals during which a failure/suspension is known to have occurred.

The area at the bottom of window shows the response columns that will be included on the Data tab, given the selections in the Life Data Response Type area.
