  1. A: anti-KLH antibody level (32 canaries measured twice), B: parasitaemia (log transformed) in infected canaries (17 canaries measured 3 times), C: haematocrit (32 canaries measured 3 times), D: body mass (32 canaries measured 3 times) and E: daily food consumption per canary per cage (16 cages measured 14 times). Minimal models are given with intercept as well as estimates, standard errors (se), t values and p values for each specific term. Non-significant terms are given with the p value of the likelihood ratio test before being dropped-out of the model
