Estimation Test Plans - Right Censoring
main topic     see also 

Stat > Reliability/Survival > Test Plans > Estimation > Right Censoring

Use the right-censoring options if your data are censored in either of these ways:

·    Time-censored -  Test each unit for a preset amount of time.

·    Failure-censored - Test the units until a preset proportion of failures occur.

Your data can be either singly censored or multiply censored:

·    Singly-censored - All of the test units run for the same amount of time or until the same percent of units fail. Units surviving at the end of the study are considered censored data.

·    Multiply-censored - Test units are censored at different times or in groups where a different percent of units are allowed to fail.

Type of Censoring

Time censor at: Choose for time-censored data, then enter the censoring time. If your data will be singly censored, enter one or more censoring times. If your data will be multiply censored, enter one or more columns of censoring times. Each row in a column represents a group of test units. See Time Censoring.

Failure censor at percent of units failed: Choose for failure-censored data, then enter the percent of failures at which to begin censoring. If your data will be singly censored, enter one or more percents. If your data will be multiply censored, enter one or more columns of percents. Each row in a column represents a group of test units. See Failure Censoring.

Allocation for Multiple Groups

Equal percent per group: Choose to run the same percentage of units for each group.

Percent of units run in each group: Choose to change the percentage of units run for each group, then enter the percentages.
