plot.SEL {SEL}

Plotting an SEL object

Description

This function displays a fitted SEL object and displays the expert's cdf or pdf (depending on the deriv argument)

Usage

## S3 method for class 'SEL'
plot(x, ..., type = c("density", "cdf"), deriv,
      points = TRUE, n = 101, xlab="", ylab="", ylim)

Arguments

x

An SEL object.

...

Additional arguments to plot function.

type

Determines whether to plot the expert's density or cdf (only if deriv is missing).

deriv

Determines which derivative of the expert's distribution should be plotted. If specified the type argument is ignored.

points

Logical indicating whether elicited quantiles should be displayed, when displaying the cdf.

n

Integer, number of points used for plotting.

xlab, ylab

Label of x-axis and y-axis.

ylim

Limits of y axis.

Examples

# example from O'Hagan et al. (2006)
x <- c(177.5, 183.75, 190, 205, 220)
y <- c(0.175, 0.33, 0.5, 0.75, 0.95)

fit <- SEL(x, y, Delta = 0.05, bounds = c(165, 250))
plot(fit)
plot(fit, type = "cdf")
plot(fit, deriv = 1)
