Statistical Models for Probabilistic Forecasting
... • This is not true if, as often happens, only a single predicted value is given. • It would be true if we use distributional assumptions about the error term, e, to construct a probability distribution for our prediction (forecast). • Creating such a probability distribution, and perhaps creating pr ...

The Simple Linear Regression Model
... We assume that E(ei |xi ) = 0, so if we could draw a scatterplot of the ei versus the xi , we would have a null scatterplot, with no patterns. We assume the errors are all independent, meaning that the value of the error for one case gives no information about the value of the error for another case ...
