Summary of a confidence envelope

Prints a useful summary of a confidence envelope of class "dbmssEnvelope"

Usage

# S3 method for class 'dbmssEnvelope'
summary(object, ...)

Arguments

object

An object of class "dbmssEnvelope".

...

Ignored.

Details

"dbmssEnvelope" objects are similar to envelope objects. Their summary is different to take into account the possibility of building global envelope following Duranton and Overman (2005): the global envelope is calculated by iteration: the simulations reaching one of the upper or lower values at any distance are eliminated at each step. The process is repeated until Alpha / Number of simulations simulations are dropped. The remaining upper and lower bounds at all distances constitute the global envelope. Interpolation is used if the exact ratio cannot be reached.

Examples

data(paracou16)

# Calculate intertype K envelope
Envelope <- KEnvelope(paracou16, NumberOfSimulations = 20, Global = TRUE,
  ReferenceType = "V. Americana", NeighborType = "Q. Rosea")
