Statistical analysis and BEST method of Kruschke for python applied on citation data in Systems Biology
The statistical analysis was performed in a jupyter notebook. This notebook contains the commands for all performed analyses (Statistical_analysis_of_FAIR_citations.ipynb)
The Bayesian Estimation Superseeds the t Test (BEST) method of Kruschke 2013 was used for the Bayesian significance testing. The method was implemented in a python class together with visualization and distributional analysis methods (BEST_method_python_Kruschke2012.py). Also the bayesian multiple comparison analysis can be found in the BEST_method_python_Kruschke2012.py file.
The results of the statistical analysis, including histograms of the data and full posterior and Posterior Predicitive Distributional (PPD) information is added in a results folder. Diagnostics according to the Bayesian Analysis Reporting Guidelines of Kruschke 2021 were added for every bayeisan estimation, including the multiple period comparison.
Methodical details can be found in the methods section of the publication.

This study investigates the citations of reproducible vs. not reproducible papers and is based on 328 published models, classified by Tiwari et al. based on their reproducibility are analyzed in this study. Hypothese testing is performed using a flexible Bayesian approach for a complete assessment of posteriors. The approach handels outliers via a non-central t distribution. Results show that reproducible papers are significantly more citet between 2013 and 2020, i.e. 10 years after the introduction ...

The Results of the analysis are structured in three parts:
- The results of the main analysis
- The results with a broader prior (Sensitivity analysis)
- The Results of the multiple period comparison
For each part, full posterior traces for all analysis and visualizations of the paper are avalable.
Furthermore the diagnostics and traces were added for the different analysis. The trace for the mulitple comparison was to large to upload it and is available on request.
The classification in reproducible and not reproducible models was made by Tiwari et al.
Citations were looked up in Scopus, Web of Science and Google Scholar.
The following journals had to be excluded, as Journal Impact Factors (JIF) were missing or papers were discontinued:
- Experientia was closed 1996 and continued as Cellular and Molecular Life Sciences 1997
- The American journal of physiology – split into fields 1977, further splits in 1980 and 1989
- IFAC Proceedings Volumes – last issue ...
The folder contains the jupyter notebook for the execution of all analyses of the study. The BEST method is used in the notebook and is added in a separate python skript.
There is a class for the BEST method according to Kruschke and a class für the BEST multiple comparison.
A conda environment file with all libraries that are necessary to perform the analysis, including the package version was created. It can be easily installed via conda env create -f pymc_env.yml
