det_thresholdfromarea_rest {highriskzone}

Determination of alpha and the threshold c which results in a high-risk zone with desired area if a hole is present.

Description

This function is used for the intensity-based method. Used in function det_hrz_restr.

Usage

det_thresholdfromarea_rest(
  intens,
  areahrz,
  win,
  nxprob = 0.1,
  hole = hole,
  integratehole = TRUE
)

Arguments

intens

estimated intensity of the observed process (object of class "im", see density.ppp)

areahrz

area of the high-risk zone

win

observation window

nxprob

probability of having unbserved events

hole

an object of class owin representing a region inside the observation window of the ppdata where no observations were possible.

integratehole

Should the hole be part of the resulting high-risk zone? Defaults to TRUE.

Value

A list of

threshold

Value of the threshold c. The high-risk zone is the field in which the estimated intensity exceeds this value

calccutoff

failure probability alpha for given area; probability to have at least unobserved event outside the high-risk zone
