What Does PRESS Stand For?

PRESS stands for Prediction Error Sum Of Squares

PRESS, or Prediction Error Sum Of Squares, is a statistical metric used to evaluate the predictive accuracy of a regression model. It quantifies the sum of the squared differences between the actual observed values and the predicted values generated by the model for a given set of data. By assessing how well a model generalizes to new, unseen data, PRESS helps in determining the model's performance and guiding improvements in model selection and validation.
