The survival analysis is a type of statistical technique to deal with data that has upper or lower limits. In this work, I demonstrate an example of applying the survival analysis to re-derive the Cepheid period-luminosity relation at 70 μm, because about 2/3 of the currently available data only contains upper limits in flux.
