set_parameter_matrix function

Set parameter matrix

Add a parameter matrix to a model

set_parameter_matrix(model, P = NULL)

Arguments

• model: A causal_model. A model object generated by make_model.
• P: A data.frame. Parameter matrix. Not required but may be provided to avoid repeated computation for simulations. See inspect(model, "parameter_matrix").

Returns

An object of class causal_model. It essentially returns a list containing the elements comprising a model (e.g. 'statement', 'nodal_types' and 'DAG') with the parameter matrix attached to it.

Examples

model <- make_model('X -> Y')
P <- diag(8)
colnames(P) <- inspect(model, "causal_types") |> rownames()
model <- set_parameter_matrix(model, P = P)
