Hi all, I would like to ask whether anyone knows if the censorReg in S-plus regress the mean survival model or the hazard and if it uses the maximum likelihood in order to estimate the values? In addition, is there anyone knowing why censorReg does not exist in R and what's the difference between censorReg and survreg (besides the truncation)? Cheers,Skevi...

Hi Group, I wonder if R has the function CensorReg which takes care of left truncation. I know it's in S. Thank you so much! Kel __________________________________________________ Do You Yahoo!?

Hi everybody, Working with interval censored data using S+, I often use the survival analysis' functions kaplanMeier() and censorReg(). Does anybody know, whether these functions exist in R, too? Thanks in advance for any answer! Saludos, Klaus. ---------------------------------------------------- Klaus Langohr Departament d?Estad?stica i Investigaci?

I am a student (and very to new to R) working on a senior design project that is attempting to determine the demand distributions for single copy newspaper draws at individual sales outlet locations. Our sales data is right-censored, because sell-outs constitute a majority of the data, and we are also testing the relevance of including covariates (weather, seasonality, economic condition, etc.).
