## S3 method for class 'stdCoxph'
plot(x, plot.CI = TRUE, CI.type = "plain", CI.level = 95,
  transform = NULL, contrast = NULL, reference = NULL, ...)

Arguments

x

an object of class "stdCoxph".

plot.CI

logical, indicating whether confidence intervals should be added to the plot.

CI.type

string, indicating the type of confidence intervals. Either "plain", which gives untransformed intervals, or "log", which gives log-transformed intervals.

CI.level

desired coverage probability of confidence intervals, in percent.

transform

a string. If set to "log", "logit", or "odds", the standardized survival function θ(t,x) is transformed into ψ(t,x)=log\{θ(t,x)\}, ψ(t,x)=log[θ(t,x)/\{1-θ(t,x)\}], or ψ(t,x)=θ(t,x)/\{1-θ(t,x)\}, respectively. If left unspecified, ψ(t,x)=θ(t,x).

contrast

a string. If set to "difference" or "ratio", then ψ(t,x)-ψ(t,x_0) or ψ(t,x) / ψ(t,x_0) are constructed, where x_0 is a reference level specified by the reference argument.

reference

must be specified if contrast is specified.

...

further arguments passed on to plot.default.
