Dear All, I am new to R. Can someone please direct me to an R package using which I can estimate a Parametric Survival Analysis model with Left-censored (delayed entry) data in it. I recently received reviewers comment on my submitted article, where the reviewer suggested that only R has capabilities of estimating above mentioned survival model. However, I am not able to figure which specific package in R, the reviewer was referring to.
Look at: ?Surv ... after loading the survival package. (I do think you would be advised to seek statistical consultation.)
In particular, notice the difference between left censoring (some patients are known to have died at an unknown time before t0) and left truncation (we only know survival times for patients alive at t0). Delayed entry is the latter.
