Big data analysis using modern statistical and machine learning methods in medicine.

Area of Science:

• Biomedical data science
• Statistical machine learning
• Bioinformatics

Background:

• Biomedical and behavioral science generate increasingly large and complex datasets annually.
• Traditional statistical analyses often struggle to integrate diverse data types like clinical, genomic, and environmental variables.
• There is a growing need for advanced statistical tools to analyze these multifaceted big datasets.

Purpose of the Study:

• Introduce modern statistical machine learning and bioinformatics approaches for analyzing big data in medicine and behavioral science.
• Discuss methods for integrating clinical, genomic (including single nucleotide polymorphism and gene expression), and environmental data.
• Highlight the utility of Bayesian networks for analyzing complex, heterogeneous biomedical datasets.

Main Methods:

• Review of established regression analyses (linear, logistic) for clinical data.
• Introduction of modern statistical models, specifically Bayesian networks.
• Exploration of methods to represent interactions among clinical, genomic, and environmental data.

Main Results:

• Modern statistical models can effectively learn relationships from large, diverse biomedical datasets.
• Bayesian networks demonstrate suitability for integrating multiple data types (clinical, genomic, environmental).
• Integration of diverse data through advanced statistical models enhances understanding of human physiology and disease.

Conclusions:

• Bayesian networks offer a powerful approach for analyzing big data in biomedical and behavioral science.
• Integrating clinical, genomic, and environmental data using modern statistical models provides a more holistic view of health and disease.
• These advanced statistical methods are crucial for advancing our comprehension of human physiology and disease mechanisms.
