Unformatted text preview: n be drawn from this analysis. However, given these reservations, it is possible to marshall both statistical and geomorphological evidence in support of the double Poisson as the more plausible explanation of karst depression formation. McConnell and Horn argue that the presence of a depression in a cell is unlikely to increase the probability of further depressions being found in that cell. They suggest that the diversion of run-off in the cell increases the efficiency of the surface drainage system and serves to enlarge the original depression rather than cause the formation of new depressions. Moreover, the acceptance of the double Poisson is made with a lower probability of Type II errors than the negative binomial.
