Diagnostic plots for mclustDensity
estimation
densityMclust.diagnostic.Rd
Diagnostic plots for density estimation. Only available for the one-dimensional case.
Arguments
- object
An object of class
'mclustDensity'
obtained from a call todensityMclust
function.- type
The type of graph requested:
"cdf"
=a plot of the estimated CDF versus the empirical distribution function.
"qq"
=a Q-Q plot of sample quantiles versus the quantiles obtained from the inverse of the estimated cdf.
- 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.- ...

Details
The two diagnostic plots for density estimation in the one-dimensional case are discussed in Loader (1999, pp- 87-90).
