- Reviewers will be asked to use the commenting function on the OSF to give precise and concise concrete feedback on the individual components. This feedback will be used to address details that need to be fixed in the study. Reviewers will also be asked to upload a file to this component that contains more general and abstract feedback on the project, giving higher-level feedback on the research. All reviews will be stored and open to our readers. When evaluating the confirmatory hypotheses for the hold out data in the cross-validation approach, reviewers will be asked to decide: - Whether the stated hypotheses are reasonably generated based on the analyses. - Whether the sample size calculation based on the exploratory analyses is reasonable. - Whether the authors’ conclusions are justified given the data. Contrary to Confirmatory Reports, reviewers will be informed that editorial decisions will be based on the perceived importance and novelty of the question being asked, but not on the conclusiveness, of the results.
