Recurrence Analysis
Model the Frequency or Cost of Recurrent Events over Time
Use the Recurrence Analysis platform to analyze event times where the events can recur several times for each unit, item, or person. The goal of the analysis is to obtain the mean cumulative function (MCF), which shows the total cost per unit as a function of time. Cost can either be a count of the number of repairs or the actual cost of a repair.
• In an industrial setting, these events can occur when a unit breaks down, is repaired, and then put back into service after the repair. The units are followed until they are ultimately taken out of service.
• In a medical setting, recurrence analysis can be used to analyze data from continuing treatments of a long-term disease, such as the recurrence of tumors in patients receiving treatment for bladder cancer.
