The document summarizes an emergency data analysis challenge presentation by Lee Shao-Fan and Yang Cheng-Han. It includes an outline, exploratory data analysis of emergency numbers over time by hospital level and individual hospitals, and a discussion of model building to predict total emergency numbers based on time, hospital, patient-doctor ratios and other factors for both hospital levels 1 and 2. Strange phenomena were noted in the emergency numbers for one hospital. Models were developed separately for hospital levels 1 and 2 to account for their differences.
