WitrynaPredict probabilities by multiplying the drawn coefficients with a specified scenario (so far these are the observed values). Take the mean and the quantiles of the simulated predicted probabilities. The presented functions follow these steps. Additionally, they use the so called observed value approach. WitrynaLogistic regression seems like the more appropriate choice here because it sounds like all of your test samples have been tested for failure (you know if they did or did not). So in that regard, there is no uncertainty in the outcome. Survival analysis is useful when you either observe the event of interest (failure) or right censoring occurred ... fort jackson ticket office disneyWitryna2 gru 2024 · After estimating a model, it is often not straight forward to interpret the model output.
