Complete the following steps to enter your data. For more information on censored data, go to Data censoring.
- In Variables, enter the columns that contain the failure times or censoring times. You can enter up to 50 columns (for 50 different samples).
- If you have frequency data for each variable, in Frequency columns (optional), enter a column that indicates the number of units for each failure time or censoring time.
- If all the samples are stacked in one column, select By variable and enter a column of grouping indicators. For example, you might enter a column to indicate different locations or a change in design.
In this worksheet, the Time column contains the failure or censoring times. The Censor column contains the censoring indicators: an F designates an actual failure time; a C designates a unit that was removed from the test, and thus censored.
