(from a regression equation): Estimate of dependent variable (y) using the regression equation. If the constant and slope, c and b, are known from the regression equation, the â€œpredictedâ€ value of y associated with a given x-value can be determined using the equation y = c + b * x. The predicted value of y is usually reported as a y with a ^ over it. All predicted values will be on the regression line. [See regression equation, residual, standard error
Prediction (also called regression) is similar to classification. The only difference is that in prediction the target attribute is not discrete but a continuous one. Prediction is processed todiscover the numerical value of the target attribute for selected examples.
A data mining technique that analyses existing data and uses the results to predict values of attributes for new records or missing attributes in existing records. For example, existing credit application data can be used to predict the credit risk for a new application.
