Re: st: OLS regression versus survival analysis
Thanks for your answer. However, I may not have been clear enough in stating my question: I meant OLS with time until the event as the dependent variable.
As to your suggestion: I have already run the KM graphs, as well as Cox regression. But then I thought: why bother if right censoring is only 3 percent... (and there are no TVCs). Especially because in this case I think the OLS interpretation makes more sense theoretically...
