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

Use interval censoring when you will be inspecting units for failures at pre-set intervals. You can space these intervals equally in time or in log time; or set intervals so that the expected number of failures in each is the same.

Dialog box items

Number of Inspections: Enter the number of inspections.

Inspection times

Equally spaced: Choose for equally spaced inspection times. In Last inspection time, enter the last inspection time.

Equal probability: Choose for the expected proportion of failures to be the same in each interval. In Total percent of failures, enter the expected percent of failures for the entire test.

Equally spaced in ln time: Choose for equally spaced natural log inspection times. In First inspection time and Last inspection time, enter the first and last times.
