Hence the RMSE is 'heavy' on larger errors. Hence there is a "conditional" bias that indicates these forecasts are tending to be too close to the average and there is a failure to pick the more extreme events. In cell A1, type “observed value” as a title. If you plot the residuals against the x variable, you expect to see no pattern.

If in hindsight, the forecasters had subtracted 2 from every forecast, then the sum of the squares of the errors would have reduced to 26 giving an RMSE of 1.47, a Hence to minimise the RMSE it is imperative that the biases be reduced to as little as possible. We can see from the above table that the sum of all forecasts is 114, as is the observations. If one was to consider all the forecasts when the observations were below average, ie.
