Using webscrapping and visualization to analyze NBA games
Playing basketball is my hobby. I enjoy playing it even though I am not good at it at all! Watching NBA games is a luxury for me.However, valuing player’s performance predicting a future star seems to be pretty interesting! The goal of this case analysis is to present a solution to scrap NBA data and to analyze using basic viausaliation techniques. Which player has the best performance? I just found something very counterintuitive!!! Will do some more analysis when I have some free time this summer!
Predictive Model for Los Angeles Dodgers Promotion and Attendance
It is tough to make good predictions. The numerous factors or variables, independent and dependent, involved in many sporting events contribute to the unpredictability. However, using carefully-selected variables, it is still possible to make marketing promotions more accountable.

Using the fitted predictive model we can predict the attendance for the game in the forthcomming season and we can predict the attendance with or without bobblehead promotion.
