WebWe can incorporate changes over time into our survival analysis by using a modification of the Cox model. The general mathematical description is: h ( t x) = b 0 ( t) ⏞ baseline exp ( ∑ i = 1 n β i ( x i ( t) − x i ¯)) ⏞ log-partial hazard ⏟ partial hazard. Note the time-varying x i ( t) to denote that covariates can change over time. http://sthda.com/english/wiki/cox-proportional-hazards-model brahma skol
