Dirichlet

ddirichlet

rdirichlet

Matrix of quantiles. Each row corresponds to one probability vector.

Matrix of positive shape parameters. Each row corresponds to one
probability vector.

alpha

Logical; If <code>TRUE</code>, values are returned on the log scale.

Number of draws to sample from the distribution.

Density function and random number generation for the dirichlet
distribution with shape parameter vector <code>alpha</code>.

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 non-linear and
smooth terms, auto-correlation structures, censored data, 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 beliefs.
Model fit can easily be assessed and compared with posterior predictive
checks and leave-one-out cross-validation. References: B<c3><bc>rkner (2017)
