Caution is required however, since limitations of the nullmodel suggest the probability of a type 2 error will be high. The dotted lines show the nullmodel for comparison. Thus, our data are consistent with the random nullmodel, suggesting that the plant-pollinator relationship in this system tends towards generalization. We tested the goodness-of-fit of the chosen model by comparing its deviance to the deviance of the nullmodel. The line indicates the best fitting model, significantly different from a nullmodel of equiprobability of fusing for each chromosome.

The dotted quantiles median and quantiles 2 show the nullmodel for comparison. To explore these discrepancies, the nullmodel is, naturally, the most informative model. Even if positive or negative associations are more numerous that predicted by a refined nullmodel, they may have several explanations. For example, assume that the parameters of interest are the parameters of the nullmodel (1). These examples are from corpora and from sources on the web.
