Pseudocode Yes Algorithm 1 Alternating updating algorithm for STORE.
Open Source Code No The paper does not contain an explicit statement about releasing source code for the described methodology, nor does it provide a link to a code repository.
Open Datasets Yes The data is from the Autism Brain Imaging Data Exchange (ABIDE), a study for autism spectrum disorder (ASD) (Di Martino et al., 2014).
Dataset Splits No The paper describes the total number of subjects and their categories (ASD vs. normal controls) for the real data analysis (795 subjects, 362 ASD, 433 normal controls) but does not specify training, validation, or test splits for this data. For simulations, it mentions varying sample sizes n {20, 100}, but not explicit dataset splits.
Hardware Specification Yes The code is written in R and is implemented on a laptop with 2.5 GHz Intel Core i7 processor.
Software Dependencies No The code is written in R and is implemented on a laptop with 2.5 GHz Intel Core i7 processor. This mentions R, but no specific version number or other software libraries with their versions are provided.
Experiment Setup Yes For STORE, the tuning parameters were chosen according to the BIC criterion in Section 3.2 by setting K = {1, 2, . . . , 10} and S = {0.1, 0.2, . . . , 0.9}. The tunings for Sparse OLS and HOLRR were conducted based on their recommended approaches.
