Hello, Can't understand some of OLS results, they don't correspond to each other. One of independent variables has a positive relationship with the depend if I look at the Coeffitient column in Summary of OLS Results table, but it has a negative relationship if I look at the Variables Distribution and Relationships graph. What result should I trust? Why there are such mismatches?
The epsilon is the residual (or error) in the prediction. Recall that OLS does not make perfect predictions, and epsilon is the difference between the true value and the predicted value.
