Question

Difference between heteroskedasticity and autocorrelation

Answer 1

Heteroskedasticity: When you study for a test, you consistently get a score between 85 and 95. When you don’t study very the results are more variable; your scores are between 60 and 90.

Autocorrelation: When you do well on a test, you do better on the next test, independent of sleep and studying.
