search for: exgauss

...I understand that the ex-Gaussian is a convolution of exponential and Gaussian distributions for survival data. I checked the "survreg.distributions" help and saw that it is possible to mix pre-defined distributions. Am I correct to think that the following code makes the ex-Gaussian:- exGauss=survreg.distributions$exponential exGauss$name='exGaussian' exGauss$dist=survreg.distributions$gaussian Am I further correct to think that I can compare the fits of the ex-Gaussian and Weibull distributions to the data via:- fit1=survreg(Surv(response)~1+frailty(unit), data=dat, dist=exGa...
