passage

The Passage Rate for each student is calculated as their Number-Right Score (NRS)
divided by the number of items presented to them. This function is applicable
only to binary response data.
The passage rate is calculated as:
$$P_i = \frac{\sum_{j=1}^J z_{ij}u_{ij}w_j}{\sum_{j=1}^J z_{ij}}$$
where:<ul>
<li>$z_{ij}$ is the missing response indicator (0/1)</li>
<li>$u_{ij}$ is the response (0/1)</li>
<li>$w_j$ is the item weight</li>
</ul>

Implements comprehensive test data engineering methods as described in
Shojima (2022, ISBN:978-9811699856). Provides statistical techniques for
engineering and processing test data: Classical Test Theory (CTT) with
reliability coefficients for continuous ability assessment; Item Response
Theory (IRT) including Rasch, 2PL, and 3PL models with item/test information
functions; Latent Class Analysis (LCA) for nominal clustering; Latent Rank
Analysis (LRA) for ordinal clustering with automatic determination of cluster
numbers; Biclustering methods including infinite relational models for
simultaneous clustering of examinees and items without predefined cluster
numbers; and Bayesian Network Models (BNM) for visualizing inter-item
dependencies. Features local dependence analysis through LRA and biclustering,
parameter estimation, dimensionality assessment, and network structure
visualization for educational, psychological, and social science research.
