A quick and dirty document on spatially correlated random effects with INLA

Some caveats on observation level random effects

A small document with example on how to test for zero-inflation and how to handle zero-inflation

Does it make sense the add a variable to both the fixed and random parts of a mixed model?

Compare lme4 and INLA in case of perfect correlation among random slopes in lme4
