survreg.old {survival} | R Documentation |
This routine is a backwards-compatible interface to the improved survreg function, which is better.
survreg.old(formula, data=sys.frame(sys.parent()), ..., link=c("log", "identity"),dist=c("extreme", "logistic", "gaussian", "exponential","rayleigh","weibull"), fixed=list())
formula |
a formula expression as for other regression models.
See the documentation for lm and formula for details.
|
data |
optional data frame in which to interpret the variables occuring in the formula. |
... |
other arguments to survreg |
link |
transformation to be used on the y variable. |
dist |
assumed distribution for the transformed y variable. |
fixed |
a list of fixed parameters, most often just the scale. |
an object of class survreg
is returned, which inherits from class glm
.
