WebDec 30, 2024 · In order to be able to compare the actual value (Y) and the predicted Y, we can create a calculation template in excel, as shown in the table below: For example, I will show you how to calculate 2011, 2012 and 2013. To calculate predicted Y in 2011, you can calculate it in the following way: Y = 218.385 – 18.161X. Y = 218.385 – 18.161(0.46) Webwhere Y is the predicted or expected value of the outcome, X is the predictor, b 0 is the estimated Y-intercept, and b 1 is the estimated slope. The Y-intercept and slope are estimated from the sample data, and they are the values that minimize the sum of the squared differences between the observed and the predicted values of the outcome, i.e., …
WebNov 21, 2024 · We need to be careful about heteroscedasticity, which indicates that the prediction errors are different for a different range of predicted values meaning that our model could be incomplete.
