calculation of alpha (failure probability), when having the threshold c
Description
This function is used for the intensity-based method. It determines the
probability to have at least one unobserved event outside the high-risk zone.
A Poisson distribution is used for the number of unobserved events in a certain area or field.
Used in functions det_threshold, det_thresholdfromarea.
Usage
det_alpha(intens, threshold, nxprob = 0.1)
Arguments
intens
estimated intensity of the observed process (object of class "im", see density.ppp)
threshold
threshold c: The high-risk zone is the field in which the estimated intensity
exceeds this value.
