Notice: The reproducibility variables underlying each score are classified using an automated LLM-based pipeline, validated against a manually labeled dataset. LLM-based classification introduces uncertainty and potential bias; scores should be interpreted as estimates. Full accuracy metrics and methodology are described in Coakley et alK. L. Coakley, T. Snelleman, H. Hoos, and O. E. Gundersen, "The embrace of open science: An analysis of a decade of AI research and 56 800 conference papers," Under Review, 2026..

Pseudocode Yes Algorithm 1: Refinement Procedure without Data Splitting; Algorithm 2: Refinement Procedure with Data Splitting; Algorithm 3: Refinement Procedure with Multiple Data Splittings
Open Source Code Yes The computation code used in Sections 5 and 6 can be found at https://github.com/yunxiaochen/Matrix Completion_Mixed Data.
Open Datasets Yes We apply the proposed method to a Movie Lens dataset for movie recommendation (Harper and Konstan, 2015). We apply the proposed method to data from the 2018 Program for International Student Assessment (PISA; OECD, 2019a)
Dataset Splits Yes To evaluate the procedures, we split the data into training and test datasets, where the training and test sets contain 80% and 20% of the observed entries, respectively. Similar to the above analysis, we split 80% and 20% of the data into training and test sets and evaluate the prediction accuracy by the test-set log-likelihood.
Hardware Specification No The paper does not explicitly describe the hardware used for running its experiments or simulations.
Software Dependencies No The paper states that computation code is available via a GitHub link, but it does not specify any software dependencies with version numbers in the text.
Experiment Setup Yes In the implementation, we set C2 = 2 p r/p in Algorithms 1, 2, and 3. We set ρ = r in the NBE and C = r in the CJMLE.
