Edge corrections are reported for the mean and variance of the average distance between a sampling point and the nearest event point in a spatial point pattern, for the case of a regular grid of sampling points. Using these corrections the point‐event analogue of the Clark‐Evans statistic is found to be a powerful detector of departures from randomness in the clustered direction.
