check_data

Wrapper function to check that<ul>
<li>all used variables are present in the <code>data</code></li>
<li>that the classes of the variables are of a type for which default model
types are defined</li>
<li>checks for empty variable levels</li>
<li>converts binary continuous variables and logical variables to factors</li>
</ul>

internal

Joint analysis and imputation of incomplete data in the Bayesian
framework, using (generalized) linear (mixed) models and extensions there of,
survival models, or joint models for longitudinal and survival data, as
described in Erler, Rizopoulos and Lesaffre (2021) <doi:10.18637/jss.v100.i20>.
Incomplete covariates, if present, are automatically imputed.
The package performs some preprocessing of the data and creates a 'JAGS'
model, which will then automatically be passed to 'JAGS'
<https://mcmc-jags.sourceforge.io/> with the help of
the package 'rjags'.
