R: Compare different elicitated densities.

comparePlot {SEL} | R Documentation

## Compare different elicitated densities.

### Description

Compare different elicitated distributions in a trellis display.

### Usage

    comparePlot(..., type = c("density", "cdf"), deriv,
                points = TRUE, superpose = FALSE, n = 101,
                xlab= "", ylab, addArgs = NULL)

### Arguments

`...` | Fitted SEL objects separated by a comma.
`type` | Determines whether to plot densities or cdfs (ignored if `deriv` is not missing).
`deriv` | Specify derivative of the expert's density to be plotted.
`points` | Logical indicating whether elicited quantiles should be displayed, when displaying the cdf.
`superpose` | Logical indicate if plots should be superposed.
`n` | Integer, number of points used for plotting.
`xlab, ylab` | Labels for x-axis and y-axis. If `ylab` is missing the value of `type` is used.
`addArgs` | List specifying additional arguments for `xyplot` function, list elements should match the corresponding arguments of the `xyplot` function.

### 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)

    default   <- SEL(x, y, Delta = 0.05, bounds = c(165, 250))
    bernst    <- SEL(x, y, d = 10, N = 0, Delta = 0.05, bounds = c(165, 250))
    unifknots <- SEL(x, y, d = 3, N = 5, Delta = 0.05, bounds = c(165, 250))
    lin       <- SEL(x, y, d = 1, inknts = x, Delta = 0.05, bounds = c(165, 250))
    comparePlot(default, bernst, unifknots, lin, type = "cdf")
    comparePlot(default, bernst, unifknots, lin, type = "density")
