ipwplot: Plot Inverse Probability Weights

In ipw: Estimate Inverse Probability Weights

Plot Inverse Probability Weights

Description

For time varying weights: display boxplots within strata of follow-up time. For point treatment weights: display density plot.

Usage

ipwplot(weights, timevar = NULL, binwidth = NULL, logscale = TRUE,
        xlab = NULL, ylab = NULL, main = "", ref = TRUE, ...)

Arguments

weights	numerical vector of inverse probability weights to plot.
timevar	numerical vector representing follow-up time. When specified, boxplots within strata of follow-up time are displayed. When left unspecified, a density plot is displayed.
binwidth	numerical value indicating the width of the intervals of follow-up time; for each interval a boxplot is made. Ignored when timevar is not specified.
logscale	logical value. If TRUE, weights are plotted on a logarithmic scale.
xlab	label for the horizontal axis.
ylab	label for the vertical axis.
main	main title for the plot.
ref	logical value. If TRUE, a reference line is plotted at y=1.
...	additional arguments passed to boxplot (when timevar is specified) or plot (when timevar is not specified).

Value

A plot is displayed.
