cor_arr

The ARR correlation structure is no longer supported.

internal

Fit Bayesian generalized (non-)linear multivariate multilevel models
using 'Stan' for full Bayesian inference. A wide range of distributions
and link functions are supported, allowing users to fit -- among others --
linear, robust linear, count data, survival, response times, ordinal,
zero-inflated, hurdle, and even self-defined mixture models all in a
multilevel context. Further modeling options include both theory-driven and
data-driven non-linear terms, auto-correlation structures, censoring and
truncation, meta-analytic standard errors, and quite a few more.
In addition, all parameters of the response distribution can be predicted
in order to perform distributional regression. Prior specifications are
flexible and explicitly encourage users to apply prior distributions that
actually reflect their prior knowledge. Models can easily be evaluated and
compared using several methods assessing posterior or prior predictions.

cor_arr function

<dl><dt>formula</dt>
<dd>A one sided formula of the form <code>~ t</code>, or <code>~ t | g</code>,
specifying a time covariate <code>t</code> and, optionally, a grouping factor
<code>g</code>. A covariate for this correlation structure must be integer
valued. When a grouping factor is present in <code>formula</code>, the
correlation structure is assumed to apply only to observations within the
same grouping level; observations with different grouping levels are
assumed to be uncorrelated. Defaults to <code>~ 1</code>, which corresponds to
using the order of the observations in the data as a covariate, and no
groups.</dd>
