interplcd {LogConcDEAD}R Documentation

Evaluate the log-concave maximum likelihood estimator of 2-d data on a grid for plotting

Description

Evaluates the logarithm of the log-concave maximum likelihood estimator on a grid for 2-d data, for use in plot.LogConcDEAD.

Usage

interplcd(lcd, gridlen=100 )
lcd.interp(lcd, gridlen=100 )  

Arguments

lcd Object of class "LogConcDEAD" (typically output from mlelcd)
gridlen A scalar indicating the size of the grid

Details

Interpolates the MLE over a grid.

The output is of a form readily usab;e by plot.LogConcDEAD, image, contour, etc, as illustrated in the examples below.

For examples, please see mlelcd.

lcd.interp is deprecated, but retained for compatibility with previous versions.

Value

x Vector of x-values of the grid
y Vector of y-values of the grid
z A matrix of the values of the log of the maximum likelihood estimator at points on the grid
