Statistical forecasting
When we describe our data, we list three basic properties of the frequency distribution. One of them is the shape of the distribution. The other two are: the independent and dependent variables a measure of central tendency and a measure of variability the variance and the standard deviation whether it is normal or skewed
In regression, what do residuals tell us? The amount of error between the predicted y-values and the actual y-values. Residuals tell us how close the predicted values are to the average of the y variable at each value of the x-variable. How much error there was in predicting the x-variable from the actual value for the x-variable. How much the predicted values for the y- variable are different from the pointof-averages.
