getConstants function

(Internal) Parse constants for adaptive test assembly simulation

getConstants is an internal function for parsing constants for adaptive test assembly simulation.

getConstants(constraints, config, arg_data, true_theta, max_info)

Arguments

• constraints: a constraints object representing test specifications. Use loadConstraints for this.
• config: a config_Shadow object. Use createShadowTestConfig for this.
• arg_data: the data argument from Shadow.
• true_theta: the true_theta argument from Shadow.
• max_info: the maximum possible information attainable by any single item in the pool. This is used to determine the M value if M is not supplied.

Returns

getConstants returns a named list containing constants.
