Navigating the world of multiple regression

“

- [Instructor] After your journey through linear regression where we highlighted the impact of a single variable, like the slope of a ramp on a skater speed, we are now ready to level up. Welcome to the big leagues, multiple regression. In this video, you'll take a look at how multiple factors work together to influence outcomes, diving deeper into the dynamics of predictive analytics. Let's pivot back to our skate park scene. But this time, you're not just looking at the ramp's slope. In multiple regression, you're considering several factors simultaneously, like skater's skill level, the wind's direction and even the skateboard's design. It's about capturing the whole scene, every element that can affect a skater's performance. In this upgraded analysis, we are extending the skate park example to include a variety of variables, starting with the ramp's slope or beta one times one. Just as before, the slope is crucial, but now it's just one of many factors. Skater's skill level, beta…
