plot.stdGee {stdReg}

Plots GEE regression standardization fit

Description

This is a plot method for class "stdGee".

Usage

## S3 method for class 'stdGee'
plot(x, CI.type = "plain", CI.level = 0.95,
  transform = NULL, contrast = NULL, reference = NULL, ...)

Arguments

x

an object of class "stdGee".

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 mean \theta(x) is transformed into \psi(x)=log\{\theta(x)\}, \psi(x)=log[\theta(x)/\{1-\theta(x)\}], or \psi(x)=\theta(x)/\{1-\theta(x)\}, respectively. If left unspecified, \psi(x)=\theta(x).

contrast

a string. If set to "difference" or "ratio", then \psi(x)-\psi(x_0) or \psi(x) / \psi(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.
