## Value

analysis_type

random

a list of the random effects formulas of the sub-model(s) for which the use had specified a formula

Mlist

a list (for internal use) containing the data and information extracted from the data and model formulas, split up into

• a named vector identifying the levels (in the hierarchy) of all variables (Mlvls)

• a vector of the id variables that were extracted from the random effects formulas (idvar)

• a list of grouping information for each grouping level of the data (groups)

• a named vector identifying the hierarchy of the grouping levels (group_lvls)

• a named vector giving the number of observations on each level of the hierarchy (N)

• the name of the time variable (only for survival models with time-varying covariates) (timevar)

• a formula of auxiliary variables (auxvars)

• a list specifying the reference categories and dummy variables for all factors involved in the models (refs)

• a list of linear predictor information (column numbers per design matrix) for all sub-models (lp_cols)

• a list identifying information for interaction terms found in the model formulas (interactions)

• a data.frame containing information on transformations of incomplete variables (trafos)

• a data.frame containing information on transformations of all variables (fcts_all)

• a logical indicator if parameter for posterior predictive checks should be monitored (ppc; not yet used)

• a vector specifying if shrinkage of regression coefficients should be performed, and if so for which models and what type of shrinkage (shrinkage)

• the number of degrees of freedom to be used in the spline specification of the baseline hazard in proportional hazards survival models (df_basehaz)

• a list of matrices, one per level of the data, specifying centring and scaling parameters for the data (scale_pars)

• a list containing information on the outcomes (mostly relevant for survival outcomes; outcomes)

• a list of terms objects, needed to be able to build correct design matrices for the Gauss-Kronrod quadrature when, for example, splines are used to model time in a joint model (terms_list)
