The work covers data understanding through source description, exploratory data analysis, and data summarization, then proceeds to model building using the tidymodels ecosystem. Model assessment emphasizes performance evaluation with ROC and AUC along with residual diagnostics. Interpretation is strengthened via variable importance, partial dependence profiles, and local explanations, followed by deployment using a Shiny application.","An R-based machine learning workflow with applications in personalized medicine  \nby  \nAshirwad Barnwal  \nA creative component submitted to the graduate faculty in partial fulfillment of the requirements for the degree of  \nMASTER OF SCIENCE  \nMajor: Statistics  \nProgram of Study Committee:  \nStephen Vardeman, Co-major Professor  \nDaniel Nordman, Co-major Professor  \nAnuj Sharma  \nSoumik Sarkar  \nThe student author, whose presentation of the scholarship herein was approved by the program of study committee, is solely responsible for the content of this creative component.
