R: Plotting an SEL object

plot.SEL

R Documentation

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)
