Y Hat Minus Y Bar

ŷ y-hat predicted average y value for a given x found by using the regression equation.

Y hat minus y bar. Defined here in Chapter 3. When working with a prediction model like a linear regression there are a few Ys you need to concern yourself with. The residual symbolized by e-sub-I equals the data point y symbolized by y-sub-I minus the predicted value from the least-squares regression line symbolized y-hat.

In statistics the explained sum of squares ESS alternatively known as the model sum of squares or sum of squares due to regression SSR not to be confused with the residual sum of squares RSS or sum of squares of errors is a quantity used in describing how well a model often a regression model represents the data being modelled. For each data point you calculate this difference which equals Y-hat-i minus Y-bar. In statistics the variable mathymath is conventionally used for observations of something you want to predict.
