summary.stdCoxph function

Summarizes Cox regression standardization fit

Summarizes Cox regression standardization fit

This is a summary method for class "stdCoxph".

## S3 method for class 'stdCoxph' summary(object, t, CI.type = "plain", CI.level = 0.95, transform = NULL, contrast = NULL, reference = NULL, ...)

Arguments

  • object: an object of class "stdCoxph".

  • t: numeric, indicating the times at which to summarize. It defaults to the specified value(s) of the argument t in the stdCox function.

  • 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, on decimal form.

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

  • contrast: a string. If set to "difference" or "ratio", then ψ(t,x)ψ(t,x0)\psi(t,x)-\psi(t,x_0)

    or ψ(t,x)/ψ(t,x0)\psi(t,x) / \psi(t,x_0) are constructed, where x0x_0 is a reference level specified by the reference argument.

  • reference: must be specified if contrast is specified.

  • ...: not used.
