Table 2.

Point estimates of beta coefficients and 95% confidence intervals (in square parentheses) from the Bayesian logistic mixed effect model testing for the effects of the three-level categorical fixed effect ‘treatment’ on genotype errors. Included are R² (the proportion of the total variance explained by the model) and marginal R² (the proportion of the total variance explained by the fixed effects alone) values.
