R package DHARMa. The ’DHARMa’ package uses a simulation-based approach to create readily interpretable scaled (quantile) residuals from fitted generalized linear mixed models. Currently supported are ’lme4’, ’glm’ (except quasi-distributions) and ’lm’ model classes. The resulting residuals are standardized to values between 0 and 1 and can be interpreted as intuitively as residuals from a linear regression. The package also provides a number of plot and test functions for typical model misspecification problem, such as over/underdispersion, zero-inflation, and spatial and temporal autocorrelation.
