Best-fit model parameter values and comparison of model fit qualities.

<p>The results for four model versions (standard = TE + NTE, Eq (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0176476#pone.0176476.e002" target="_blank">2</a>); TE-only = NTE parameters <i>b</i> and <i>q</i> were set to zero; NTE-only = TE parameter <i>a</i> was set to zero; TDR = time-dependent dose rate, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0176476#pone.0176476.e015" target="_blank">Eq 14</a>) are arranged in columns. ΔAICc and Akaike weight are information theoretic metrics of relative model performance: the model with the highest support from the data among all tested models has the lowest ΔAICc and the highest weight. Details are discussed in the main text.
