solution

Consider the model you developed in question 8 of Chapter 8 and perform a simulation to see if the model you developed adequately describes the response variable data distribution. A potential problem with this data set is the limited variability in the response variable. This could be caused by the difficulty in accurately recording the number of mates a frog had; either the duration of observation is too short, or there might be mates that were not observed. The consequence of this problem is the underreporting of the number of mates, and the resulting model is likely to underestimate the number of mates (and producing too many 0s). Arnold and Wade [1984] discussed other problems with such data.
