det_threshold {highriskzone}

Calculation of the threshold c, when having failure probability alpha.

Description

The high-risk zone is the field in which the estimated intensity exceeds the threshold c, which is determined here, having the failure probability alpha. This function is for the intensity-based method. Used in function det_hrz.

Usage

det_threshold(intens, alpha = 1e-05, nxprob = 0.1)

Arguments

intens

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

alpha

failure probability: probability to have at least one unobserved event outside the high-risk zone

nxprob

probability of having unobserved events

Value

value of the threshold c
