Data Types for Crow Extended Model

You can apply the Crow Extended model to any of the following data types.

• All times-to-failure data types

• Discrete Mixed data

• All fielded data types

When the Crow Extended model is selected in any of these data sheets, additional Classification and Mode columns will appear in the data sheet. These columns are used to classify and identify the failure mode responsible for each observed failure. To learn how to use these two columns in an analysis, see Failure Mode Classifications.
