My Code:
sigMod <- coxph(Surv(time, DEATH_EVENT) ~ age+anaemia+creatinine_phosphokinase+ejection_fraction+
serum_creatinine+hypertension, data=HF)
ggcoxdiagnostics(sigMod, type = "martingale",
linear.predictions = FALSE,
ggtheme = theme_bw(),
)
There is an observation at around the 50-line mark with an extreme residual at the bottom of the graph. How would I go about getting it?
