Check model singularity

Source: R/check_gazepoint_model_singularity.R
check_gazepoint_model_singularity.Rd

Check whether a fitted mixed model has a singular random-effects structure.

Usage

check_gazepoint_model_singularity(model, tolerance = 1e-04, model_name = NULL)

Arguments

model

A fitted model object, or a gp3tools fit object containing a $model element.

tolerance

Numeric tolerance passed to lme4::isSingular().

model_name

Optional model label used in the returned table.

Value

A tibble with model class, singular-fit status, diagnostic status, and message.

Details

This helper is primarily intended for lme4 mixed models. For model classes where singularity is not meaningful, such as lm, glm, and mgcv GAM objects, it returns a structured not_applicable diagnostic row.
