WebWhile OLS remains computationally feasible and can be easily used while doing any econometrics examination, it lives critical to know the underlying assumption of OLS regression. This is because a lack of knowledge of OLS assumptions would result in its misuse and invite incorrect results available aforementioned econometrics test completed. WebIndependent Trials Assumption: The trials are independent. If we are tossing a coin, we assume that the probability of getting a head is always p = 1/2, and that the tosses are independent. This assumption seems quite reasonable, but it is unverifiable. There’s no condition to test; we just have to think about the situation at hand.
