Predicted y value
WebHere we look at any specific value of x, x 0, and find an interval around the predicted value ŷ 0 for x 0 such that there is a 95% probability that the real value of y (in the population) … 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., …
