C prediction interval calculator
WebThis calculator is built for simple linear regression, where only one predictor variable (X) and one response (Y) are used. Using our calculator is as simple as copying and … WebIn both cases, the intervals will be narrowest near the mean of x and get wider the further they move from the mean. The differennce between them is that a confidence interval gives a range for the expected value of y. A prediction interval gives a range for the predicted value of y. Confidence intervals will be narrower than prediction intervals.
