What does it mean to be the GOAT of women's tennis? Is it an unbeatable statistic, winning the most matches, grand slam titles, or something more intangible? Join us as we use Dataiku to explore critical tennis statistics such as first serve won, first return point won, and break points saved. Based on these findings, we will then walk through models built to group together players with similar statistics, then forecast the winner in a two-player matchup. Finally, we will see if we can determine who the next GOAT might be in women's tennis!
