What is survreg in R?

What is survreg in R?

The survreg function in R runs parametric accelerated failure time (AFT) models. The key assumption is that survival time accelerates (or decelerates) by a constant factor when comparing different levels of covariates.

What is parametric survival analysis?

A parametric survival model is a well-recognized statistical technique for exploring the relationship between the survival of a patient, a parametric distribution and several explanatory variables. It allows us to estimate the parameters of the distribution.

What package is Coxph in R?

The function coxph()[in survival package] can be used to compute the Cox proportional hazards regression model in R. formula: is linear model with a survival object as the response variable.

How to use survreg regression in survival analysis?

survreg: Regression for a Parametric Survival Model In survival: Survival Analysis. Description. Fit a parametric survival regression model. These are location-scale models for an arbitrary transform of the time variable; the most common cases use a log transformation, leading to accelerated failure time models.

How to fit a parametric survival regression model?

Fit a parametric survival regression model. These are location-scale models for an arbitrary transform of the time variable; the most common cases use a log transformation, leading to accelerated failure time models.

Which is the response of the SURV function?

The response is usually a survival object as returned by the Surv function. See the documentation for Surv, lm and formula for details. a data frame in which to interpret the variables named in the formula, weights or the subset arguments. a missing-data filter function, applied to the model.frame, after any subset argument has been used.

Which is an element of a survreg distribution?

If the argument is a character string, then it is assumed to name an element from survreg.distributions. These include “weibull”, “exponential”, “gaussian” , “logistic”, “lognormal” and “loglogistic” . Otherwise, it is assumed to be a user defined list conforming to the format described in survreg.distributions . a list of fixed parameters.
