WebTable 2 shows the fits of model (1) to the data presented in Table A3 by the REML and ML methods respectively. The between day variance components obtained by REML and ML methods are 1.684 × 10 ... WebML differs from REML in how the random effects are estimated and p-values computed for the fixed effects. (Note that ML is not available for combined split-plot designs.) REML is the default in most cases because it provides unbiased estimates, while ML is only unbiased for large designs. In the software, this threshold is defined by the ...
