MirtCAT

Wraps the mirtCAT R package.

ComputerAdaptiveTestingExt.MirtCAT.make_mirtcat — Function

make_mirtcat(
    mirt_params;
    criteria,
    method,
    start_item,
    design,
    quadpts,
    theta_range
)

Makes an MirtCatDesign object from the given mirt_params which can be any supported implementation for FittedItemBanks.AbstractItemBank or a raw R object supported by mirtCAT's mo argument.

The criteria, method, start_item, design, quadpts and theta_range arguments will be passed directly to R mirtCAT function.

The return value is tuple of the MirtCatDesign object, and the raw R object passed as the mo argument for the item bank.

ComputerAdaptiveTestingExt.MirtCAT.MirtCatDesign — Type

mutable struct MirtCatDesign{T}

A type wrapping an mirtCAT mirtCAT_design object.

ComputerAdaptiveTestingExt.MirtCAT.StatefulMirtCat — Type

abstract type StatefulMirtCat <: ComputerAdaptiveTesting.Stateful.StatefulCat

Supertype for StatefulMirtCatNoRollbacks and StatefulMirtCatWithRollbacks

source

ComputerAdaptiveTestingExt.MirtCAT.StatefulMirtCatNoRollbacks — Type

struct StatefulMirtCatNoRollbacks{T} <: ComputerAdaptiveTestingExt.MirtCAT.StatefulMirtCat

StatefulMirtCatNoRollbacks(design::MirtCatDesign) -> StatefulMirtCatNoRollbacks

Adapter type for MirtCatDesign into a ComputerAdaptiveTesting.Stateful implementation. This implementation does not support rollbacks.

source

ComputerAdaptiveTestingExt.MirtCAT.StatefulMirtCatWithRollbacks — Type

struct StatefulMirtCatWithRollbacks{T} <: ComputerAdaptiveTestingExt.MirtCAT.StatefulMirtCat

StatefulMirtCatWithRollbacks(design::MirtCatDesign) -> StatefulMirtCatWithRollbacks

Adapter type for MirtCatDesign into a ComputerAdaptiveTesting.Stateful implementation supporting rollbacks. This implementation uses deep copies to support rollbacks an may consume a lot of memory.
