Mixed-effects model testing for the influence of body mass, temperature, time of day, rearing environment, and measuring environment on oxygen consumption of tadpoles.

The model included the rearing pool as random factor. Estimates and test statistics are the coefficient and t-value for fixed effects, and the variance component and LR statistic for the random effect. Significance of fixed effects was judged from 10,000 Markov chain Monte Carlo samples drawn from the posterior distribution of the parameters in a Bayesian version of the model.
