Selections observed | Selections expected | P | |
---|---|---|---|

GEM vs. linear model | 41 (75%) | 2.75 | 1.97 × 10^{−41} |

GEM vs. exponential model | 40 (73%) | 2.75 | 1.02 × 10^{−39} |

GEM vs. exponential + a constant model | 8 (15%) | 2.75 | 0.0116 |

Exponential + a constant model vs. exponential model | 41 (75%) | 2.75 | 1.97 × 10^{−41} |

*n*= 55. Two-sided*P*values were calculated by the binomial proportions test for the proportion of times the first model was selected over the second model in comparison to the number of selections expected.
