The probability of the three models given the data.

<p><b>AB</b> The log-likelihood differences between the models, using the Difference model as a baseline. Note the small error bars, representing two standard-errors, given by running the algorithm 10 times, and each time using 1000 samples to estimate the model evidence (<a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1004519#pcbi.1004519.e040" target="_blank">Eq (25)</a>). <b>CD</b> The posterior probability of the models, assuming a uniform prior. Left column, one response. Right column, two responses.
