densityMclust.diagnostic: Diagnostic plots for `mclustDensity` estimation

Description

Diagnostic plots for density estimation. Only available for the one-dimensional case.

Usage

densityMclust.diagnostic(object, type = c("cdf", "qq"),  col = c("black", "green4"),  lwd = c(2,2), lty = c(1,2),  legend = TRUE, grid = TRUE,  main = TRUE, ...)

Arguments

object

An object of class 'mclustDensity' obtained from a call to densityMclust function.

type

The type of graph requested:

col

A pair of values for the color to be used for plotting, respectively, the estimated CDF and the empirical cdf.

lwd

A pair of values for the line width to be used for plotting, respectively, the estimated CDF and the empirical cdf.

lty

A pair of values for the line type to be used for plotting, respectively, the estimated CDF and the empirical cdf.

legend

A logical indicating if a legend must be added to the plot of fitted CDF vs the empirical CDF.

grid

A logical indicating if a grid should be added to the plot.

main

A logical indicating if a title should be added to the plot.

...

Additional arguments.

Examples

Run this code

x = faithful$waiting
dens = densityMclust(x)
## Not run: 
# plot(dens, x, what = "diagnostic")## End(Not run)
# or
densityMclust.diagnostic(dens, type = "cdf")
densityMclust.diagnostic(dens, type = "qq")
