Auto Group Data

The Auto Group Data tool is available for both Weibull++ and ALTA standard folios. It allows you to automatically group together identical data points. This helps to speed up calculations when you have a large data set.

In Weibull++, two data points are considered identical if their failure/suspension times AND the value/text in their Subset IDs columns are identical.

In ALTA, two data points are considered identical if their failure/suspension times AND stress levels AND the value/text in their Subset IDs columns are identical.

Note: The subset ID can be any text up to 30 characters, including spaces. For example, “A _ _ X” is not the same as “A _ X” where “ _ ” is used to designate a space.

To group your data, click the Auto Group Data icon on the Main page of the control panel.

You can choose to group exactly identical values, or to first round the failure/suspension times to the nearest whole number or multiple of 10 and then group the identical data.
