This model allows for the evaluation of the average effect of single management practices by accounting for year-to-year variability, region within year variability, and management practice nested within region within year variability. However, because the default random number generator settings may change between MATLAB releases, using 'default' does not guarantee predictable results over the long-term. 'default' is a convenient way to reset the random number generator, but for even more predictability, specify a generator type and a seed. Committed to publishing great books, connecting readers and authors globally, and spreading the love of reading.

(This definition is confusing, and I would happily accept a better one.) A classic example is crossed temporal and spatial effects.

Predicted values are conditioned on the zero-inflation component and take the random effects uncertainty into account. For models fitted with glmmTMB(), hurdle() or zeroinfl(), this would return the expected value mu*(1-p).
