Enter your data

Complete the following steps to enter your data. For more information on censored data, go to Data censoring.

  1. In Variables, enter the columns that contain the failure times or censoring times. You can enter up to 50 columns (for 50 different samples).
  2. 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.
  3. If all the samples are stacked in one column, select By variable and enter a column of grouping indicators.
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.

For information on how to enter the censoring values for the analysis, see the topic "Specify the censoring options".

Assumed distribution

Select a distribution to model your data. Base your decision on process knowledge or use probability plots to evaluate the model fit. For more information, go to Distribution fit for reliability analysis.
