plotRetentionArea: Plots the convex increasing retention area

In evidenceFactors: Reporting Tools for Sensitivity Analysis of Evidence Factors in Observational Studies

Description

For two evidence factors this function produces a grey-scale plot of the retention set, i.e. the set of sensitive bias levels.

Usage

plotRetentionArea(retentionBrd, Gamlist, ...)

Arguments

retentionBrd	Output of retentionBrd function for two evidence factors.
Gamlist	List of two vectors of gamma values for two evidence factors.
...	Further arguments to be passed to method image and legend used for plotting.

Details

For 2 evidence factors plotRetentionArea produces a grey-scale plot of the retention set, i.e. the set of sensitive bias levels.

Value

The output of the function is plot.

data(Gamlist)
rbrd = retentionBrd(Plist, Gamlist)
plotRetentionArea(rbrd, Gamlist)

rbrd = retentionBrd(Plist, Gamlist, method = "Truncated")
plotRetentionArea(rbrd, Gamlist)

## mean tail moment data example
