I landed a corporate job by working up the ladder in the operation side of the business, and while im a smart cookie, I never finished college and hated math in school. Your simple and practical videos help me keep toe to toe with people who have masters or MBAs. Thank you!!!!
That's very subjective depending on the data. The R squared value represents the amount of the variation in the dependent variable that can be explained by the independent variable. If you've got a value of less than 0.5 then over half the variation will be unexplained which isn't great. Obviously, the higher the value the better.
You have explained in 10 minutes what certain Columbia University professors failed to explain in an entire semester. Dude, raise your hourly rate, please!
