main effects model
Select for a design with two factor design for a main effects model
interaction model
Select for a design with two factor design for a model that contains main effects and an interaction term for the two factors.
Monitoring at Intervals
Assumes that units are inspected for failures at intervals. Failure times are interval censored. Enter the number of inspections, the time of the first inspection, and a time between inspections. For inspection intervals that are irregular, you can change the inspection times later in the Design Choices outline.
Continuous Monitoring
Assumes that exact failure times are recorded. Failure times beyond the length of the test are right censored.
