Surv and survfit seem to be from the survival package; surv_median appears to be from the survminer function. In addition, your code refers to a column named "status" but this column is not in your provided dataset. Finally, if you want us to tinker with your code to ...

WebData for survival analysis. The simplest data structure for a typical survival analysis is: single row per subject; a status variable coding whether the subject experienced the event or not (censored) single time variable measuring \(T\) time to event (or censoring time, time of last observation) WebOnce we fit a Weibull model to the test data for our device, we can use the reliability function to calculate the probability of survival beyond time t. 3. R ( t β, η) = e − ( t η) β. Note: t = the time of interest (for example, 10 years) β = the Weibull scale parameter. η = the Weibull shape parameter. brewer long term care
