[R] How to get the hazard of coxph (not cumulative hazard)

Dear all, I think the coxph and survfit.coxph can give the cumulative hazard of cox model. But is there any method to calculate the hazard Lambda(t)=lambda_0(t)*exp{beta*X(t)}? Any suggestion will be great help. Thank you very much! Koshihaku -- View this message in context: http://r.789695.n4

[R] Is the output of survfit.coxph survival or baseline survival?

t mean the survival is estimated by the value of covariates in the new data frame? Thank you very much! Koshihaku -- View this message in context: http://r.789695.n4.nabble.com/Is-the-output-of-survfit-coxph-survival-or-baseline-survival-tp3861919p3861919.html Sent from the R help mailing list

Re: [R] How does the survfit.coxph calculate the survival value?

all the six covariates in my model are time-dependent. Could you please give me any opinion on this? Koshihaku -- View this message in context: http://r.789695.n4.nabble.com/How-does-the-survfit-coxph-calculate-the-survival-value-tp3847179p3853994.html Sent from the R help mailing list archive

[R] Does the bashaz give the breslow estimator of baseline hazard?

estimator for baseline cumulative hazard. If basehaz does not give me breslow estimator, please advise on how I can get it. Thanks for any suggestion given. kind regards, Koshihaku -- View this message in context: http://r.789695.n4.nabble.com/Does-the-bashaz-give-the-breslow-estimator-of

[R] How does the survfit.coxph calculate the survival value?

Sorry for a long question. I am in an urgent using R to fit the cox proportional model. My data is a data frame including 100 individuals which are software stress tests. There are time-to-failure and six covariates meaning the system resource (every 4 minutes). Is it possible to use R to fit the
