Results for GLMM analyses of the South Coast penguin colony chick condition data

Download (842.95 kB)
The GLMM model to estimate the impact of fishing on penguins at the St Croix and Bird Island colonies is applied to the South Coast chick condition data. The results indicate a negative impact for St Croix and a mixed impact for Bird Island in terms of point estimates. However, none of these estimates is statistically significant, and standard errors of the estimates are large, ranging from 0.23 to 0.45, so that any inferences drawn from this analysis would not have great reliability.
