Descriptive statistics for the variables predicting the binomial outcome: dead or live salmon lice in bioassays with exposure to azamethiphos or deltamethrin.

ΔAIC represents the difference in AIC values when omitting the given variable from the final regression model (Table 4) with an AIC of 17889 (not given for Farm bath-treatments since this was not part of the final model).

ΔAIC指代从最终回归模型（表4）中剔除给定变量后的赤池信息准则（Akaike Information Criterion，AIC）值之差，该最终模型的AIC为17889；农场水浴处理（Farm bath-treatments）因未被纳入该最终模型，故未给出其AIC值。
