Value

analysis_type

lm, glm, clm, lme, glme, clmm, survreg or coxph with attributes family and link

data

the original (incomplete) dataset

models

named vector specifying the models used for longitudinal and incomplete covariates

fixed

supplied fixed effects formula

random

supplied random effects formula

Mlist

a list: containing the data, split up into

• outcome (y)

• censoring indicator for survival outcomes (cens)

• cross-sectional main effects (Xc)

• cross-sectional interactions (Xic)

• longitudinal main effects (Xl)

• longitudinal interactions (Xil)

• categorical cross-sectional incomplete variables (Xcat)

• categorical longitudinal variables (Xlcat)

• transformed cross-sectional variables (Xtrafo)

• random effects design matrix (Z)

and other important specifications:

• a list naming which columns of the above matrices are covariates in the analysis model (cols_main)

• a list giving the names of the covariates in the analysis model per matrix (names_main)

• specification for transformations (trafos)

• specification for hierarchical centering (hc_list)

• reference values and dummies for categorical variables (refs)

• vector of auxiliary variables (auxvars)

• grouping specification (groups)

• the vector of variables to be scaled (scale_vars)

• updated fixed effects structure (fixed2)

• the number of categories if the outcome of the analysis model is categorical (ncat)

• the number of subjects (N)

• whether posterior predictive checks are be enabled ppc (not yet used)

• whether ridge shrinkage priors should are used for the regression coefficients of the analysis model (ridge)

• the number of random effects (nranef)
