@bugs(program::Expr)
@bugs(program::String; replace_period::Bool=true, no_enclosure::Bool=false)

Constructs a Julia Abstract Syntax Tree (AST) representation of a BUGS program. This macro supports two forms of input: a Julia expression or a string containing the BUGS program code.

• When provided with a string, the macro parses it as a BUGS program, with optional arguments to control parsing behavior.
• When given an expression, it performs syntactic checks to ensure compatibility with BUGS syntax.

Arguments for String Input

For the string input variant, the following optional arguments are available:

• replace_period::Bool: When set to true, all periods (.) in the BUGS code are replaced. This is enabled by default.
• no_enclosure::Bool: When true, the parser does not require the BUGS program to be enclosed within model{ ... } brackets. By default, this is set to false.

compile(model_def, data[, initial_params])

Compile the model with model definition and data. Optionally, initializations can be provided. If initializations are not provided, values will be sampled from the prior distributions.

initialize!(model::BUGSModel, initial_params::NamedTuple)

Initialize the model with a NamedTuple of initial values, the values are expected to be in the original space.

initialize!(model::BUGSModel, initial_params::AbstractVector)

Initialize the model with a vector of initial values, the values can be in transformed space if model.transformed is set to true.
