getInfoFixedTheta function

(Internal) Precalculate item information for fixed-theta item selection methods

getInfoFixedTheta is an internal function for calculating item information for fixed-theta item selection methods. This is done once at the start of the simulation and cached for speed gain.

getInfoFixedTheta(item_selection, simulation_constants, item_pool, model)

Arguments

• item_selection: a list containing item selection config.
• simulation_constants: a named list containing simulation constants.
• item_pool: an item pool object.
• model: sanitized item model codes to be fed to C++ functions.

Returns

getInfoFixedTheta returns a named list containing item information values at designated thetas for each simulee.
