interplcd {LogConcDEAD} | R Documentation |
Uses the akima package to evaluate the logarithm of the
log-concave maximum likelihood estimator on a grid for 2-d data, for
use in plot.LogConcDEAD
.
interplcd(lcd, gridlen=100, span=0.5, ...) lcd.interp(lcd, gridlen=100, span=0.5, ...)
lcd |
Object of class "LogConcDEAD" (typically output from mlelcd ) |
gridlen |
A scalar indicating the size of the grid |
span |
Scalar parameter needed by interp
(see interp for more details) |
... |
Other arguments to be passed to interp |
Uses the akima package's
interp
function to evaluate the log-concave maximum likelihood estimator on a grid covering the span of the data.
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.
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 |
Needs the akima package.
