Description

summary method for class "dlc".

Usage

1
2
## S3 method for class 'dlc'
summary(object, ...)

Arguments

object

An object of class "dlc", usually a result of a call to logConDens.

...

Further arguments.

Details

See activeSetLogCon and evaluateLogConDens for details on the computations.

Value

The function summary.dlc returns a list of summary statistics of the estimated log-concave density as well as of its smoothed version (depending on the value of smoothed when calling logConDens).

Warning

Note that the numbering of knots in the output relies on the vector of unique observations.
