Fields

num_tune: u64

The number of tuning steps, where we fit the step size and mass matrix.

num_draws: u64

The number of draws after tuning

maxdepth: u64

The maximum tree depth during sampling. The number of leapfrog steps is smaller than 2 ^ maxdepth.

store_gradient: bool

Store the gradient in the SampleStats

store_unconstrained: bool

Store each unconstrained parameter vector in the sampler stats

max_energy_error: f64

If the energy error is larger than this threshold we treat the leapfrog step as a divergence.

store_divergences: bool

Store detailed information about each divergence in the sampler stats

adapt_options: TransformedSettings

Settings for mass matrix adaptation.

check_turning: bool

num_chains: usize

seed: u64
