Preregistration is a document detailing the background of this project and the methods that will be used. script1_sampling is the script that will allow to sample from the larger bibliography. script2_checking is the script that will let us check the correct articles were downloaded for each subsample, input full publication date information, and write a file containing Article ID number and correspondong references for the full sample. To test the script and render it in HTML, script2_checking was run using the file at https://osf.io/wf4z7/ under the name check_bibliography_1.csv. script3_joining is the script that combines all datasets from the previous and current research, and writes a file that will be used for the analysis. To test the script and render it in HTML, script3_joining uses the data simulated by https://osf.io/6qfa5/. The file sim.bib.csv is called directly. The file sim.data.csv is called under the name sample_coded.csv. script4_descriptives computes sample sizes and other simple descriptives. script5_models is the script that carries out the analyses described in the preregistration document.
