  • The data of baseball players here
  • The project has following subsection:
    • Data quality analysis
    • Data Cleaning
    • Exploratory Data Analysis
    • Building model for players salary (linear regression is used)
    • Predicting if a player will hit/not hit (Logistic regression is used)
    • References
