Standardized residuals from Parametric Survival Fit Platform

Hi everyone,

 

I would like to know more about the residuals from the Parametric Survival Fit platform.

 

If I use this platform and plot the residuals (Residual Probability Plot), I get a plot with Standardized Residual in the X-axis and the probability in the Y-axis.

 

Does anyone know the formula of the Standardized Residual?

Is it the Cox-Snell Residual?

 

Thanks,

It may provide you with the statistical detailsRe: Standardized residuals from Parametric Survival Fit Platform

Hi Txnelson,

 

Thanks for your idea, I didn't know this way of doing (I'll keep in mind). Unfortunately, the help page does not contain information on my problem.

 

Thanks anyway,

 

 

Re: Standardized residuals from Parametric Survival Fit Platform

For location-scale distributions (i.e. Normal, Logistic, SEV, LEV), the formula is (Y - mu(X))/sigma(X).

For log-location-scale distributions (i.e. Lognormal, Loglogistic, Weibull, Frechet, Exponential), the formula is Exp((Log(Y) - mu(X))/sigma(X)).

In both formulas, mu(X) and sigma(X) are linear functions of the covariates, depending on how your model is set up.

It is a type of Cox-Snell residual.
