Hi everyone,
I would like to conduct a Kaplan-Meier Survivorship analysis with JMP (version 15.2.1). I want the confidence intervals to be calculated with the Greenwood log-log approach. But I am not sure which formula JMP uses and I cannot find anything about that.
Does anyone know if the upper and lower 95% values in the JMP survival analysis is calculated with the Greenwood log-log approach? If it is calculated in a different way, is it possible to set the calculation method somewhere in JMP?
