get_mixed_info: Extract various information from mixed models

In insight: Easy Access to Model Information for Various Model Objects

Extract various information from mixed models

Description

Small helper function that returns essential information on coefficients, model matrix, variance and correlation parameters, as well as random effects parameters of mixed effects models as list. Mainly used for internal purposes.

Usage

get_mixed_info(model, ...)

## Default S3 method:
get_mixed_info(model, verbose = TRUE, ...)

## S3 method for class 'glmmTMB'
get_mixed_info(model, component = "conditional", verbose = TRUE, ...)

Arguments

model	A mixed effects model.
...	Not used.
verbose	Toggle off warnings.
component	For glmmTMB and MixMod models, this argument specifies the component of the model to extract. Possible values are "conditional" (default) and "zero_inflated" (or "zi").

Value

This function returns a list that has the same structure for any mixed models with the following components:

• beta (contains fixed effects, as returned by lme4::fixef(model))

• X (contains the model matrix, as returned by lme4::getME(model, "X"))

• vc (contains the variance and correlation parameters, as returned by lme4::VarCorr(model))

• re (random effects parameters, as returned by lme4::ranef(model))
