WebThe left-hand variable is a vector in the n-dimensional space. Each column of X (regressor) is a vector in the n-dimensional space as well, and we have k of them. Then the subspace spanned by the regressors forms a k-dimensional subspace of the n-dimensional space. The OLS procedure is nothing more WebIt is a property of OLS that the residuals must sum to zero if there is a constant or the equivalent in the model, but all of the data points are above the regression fit except one, which is only slightly below, in the first two figures. This is mathematically impossible.
