[R-sig-ME] glmer not supported class for vuong()closeness test (non-nested models)

[Mollie Brooks]

If you want to use vuong() to test for zero inflation, then an alternative would be to use testZeroinflation() from the DHARMa package which supports glmer models. It performs a different test using simulated residuals.

See documentation here

Cheers,
Mollie
