Table 3.
Parameter settings of regression coefficients (b) and variance components (σ2) for five datasets: (1) fecundity, (2) endoparasite, (3) size, (4) exploration and (5) morph; all parameters are set on the latent scale apart from the size data (see below).
| response | intercept (b) | sex (b) | treatment (b) | habitat (b) | population (ς2) | container (ς2) | overdispersion (ς2) |
|---|---|---|---|---|---|---|---|
| fecundity: the number of eggs per female | 1.1 | — | 0.5 | 0.1 | 0.4 | 0.05 | 0.1 |
| parasite: the number of endoparasites per individual | 1.8 | −2 | −0.8 | 0.7 | 0.5 | 0.8 | — |
| size: the body length of an individuala | 15 | −3 | 0.4 | 0.15 | 1.3 | 0.3 | 1.2 |
| exploration: the time taken visiting five sectors for an individual | 4 | −1 | 2 | −0.5 | 0.2 | 0.2 | — |
| morph colour morph of a male | −0.8 | — | 0.8 | 0.5 | 1.2 | 0.2 | — |
aData for the six sets of models were simulated on the normal (Gaussian) scale but analysed assuming a gamma error structure with the log link so that estimations of these parameters will be on the log scale; note the overdispersion variance for this data is the residual variance.
