fwdmvQuantilePlot {Rfwdmv}R Documentation

Plot Trajectories over Quantiles of the Distances

Description

Produces a 6 panel plot. The first panel contains the Mahalanobis distances for the units in the subset of size subset.size. The backgrounds of the 5 remaining plots are quantiles of these distances. The dark lines in the 5 remaining plots are the trajectories of the units entering the subset during each of the next 5 steps of the forward search.

Usage

fwdmvQuantilePlot(x, subset.size, probs = "default", page = 1)

Arguments

x an fwdmv object.
subset.size an integer specifying (by its size) the subset to be used in the first panel.
probs an ordered numeric vector of probabilities used by the quantile function.
page an integer specifying the page. When page == 1 the trajectories for the next 5 steps are drawn, when page == 2 the next 5 steps are skipped and trajectories for the 5 following step are drawn, etc.

Details

when probs == "default" the following quantiles are computed: 0.025, 0.05, 0.125, 0.25, 0.50, 0.75, 0.875, 0.95, 0.975.

Value

an empty list is invisibly returned.
