Simulated 1-3-3 MST panel data

Description

This simulated 1-3-3 MST panel data set was used in Lim et al.' (2020) simulation study.

Usage

simMST

Format

This data set includes a list of five internal objects:

item_bank

The item bank metadata, containing item parameters and other information.

module

A binary matrix that maps items from the item bank to modules within the MST panel. This parameter enables precise item-to-module assignments for MST configurations, analogous to the modules argument in the randomMST function of the mstR package (Magis et al., 2017).

route_map

A binary square matrix that defines the MST structure, illustrating transitions between modules and stages. This concept is inspired by the transMatrix argument in the randomMST function from the mstR package (Magis et al., 2017).

cut_score

A list defining cut scores for routing test takers through MST stages. Each list element is a vector of cut scores for advancing test takers to subsequent stage modules.

theta

A vector of ability levels (theta) at which the MST panel's performance is assessed, allowing for the evaluation of measurement precision across a continuum of ability levels.

This 1-3-3 MST panel consists of 7 modules in total with 3 stages. Each module contains eight items calibrated with the IRT 3 parameter logistic model.
