Dear R-user: I am using survreg(Surv()) for fitting a Tobit model of left-censored longitudinal data. For logarithmic transformation of y data, I am trying use survreg.distributions in the following way: tfit=survreg(Surv(y, y>=-5, type="left")~x + cluster(id), dist="gaussian", data=y.data, scale=0, weights=w) my.gaussian<-survreg.distributions$gaussian my.gaussian$name="lognormal" my.gaussian$dist<-my.gaussian tfit=survreg(Surv(y, y>=-5, type="left")~x + cluster(id), dist=my.gaussian, data=y.data, scale=0, weights=w) If I run these codes then I got the following error message, Error in survreg(Surv(y, y >= -5, type = "left") ~ x + : Invalid distribution object
Does anybody can help me in identifying the error(s) in these code please? Advance thanks for your time.
