det_alpha
(Package: highriskzone) :
calculation of alpha (failure probability), when having the threshold c
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.
