Hi experts, http://r.789695.n4.nabble.com/file/n4034318/Parametric_survival_analysis_2nd-order_efffect.JPG Parametric_survival_analysis_2nd-order_efffect.JPG As we know a normal survival regression is the equation (1) Well, I'ld like to modify it to be 2nd-order interaction model as shown in equation(2)
Question: Assume a and z is two covariates. x = dummy variable (1 or 0) z = factors (peoples' name) fit <- survreg(Surv(time,censor)~x*z, data=sample, dist="exponential") I tried to apply survreg(), while I have few questions: 1) If */survreg(Surv(time,censor)~x*z, data=sample, dist="exponential")/* correct? 2) If the baseline hazard is the value excluded both x and z effects? 3) How can I get the value and plot the hazard with only x effect (but exclude effect z) Thanks Best, Ryusuke -- View this message in context: http://r.789695.n4.nabble.com/Second-order-effect-in-Parametric-Survival-Analysis-tp4034318p4034318.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
