Dear all,I'm a newbie to Survival Analysis and I have some questions about the
functions in the survival package.First, what's the difference between survreg
and coxph? Say fit1<- survreg(survObj ~ var1 + var2 + var3, dist= 'whatever')
and fit2<- coxph(survObj ~ var1 + var2 + var3), what's the difference between
fit1 and fit2? They all do regression on explanatory variables. What does it
mean dist in survreg?Second, what's the difference in these two specifications
of the proportional hazard model?coxph(survObj ~ var1 +
strata(var2))coxph(survObj ~ var1*strata(var2))Thanx,Pierre
