... simple linear regression model appears to approximately hold with the regression line approximately going through the origin and there is a reasonably high correlation between y and x (say above 0.5), then the ratio or the regression estimator is reasonable. If a simple linear regression model appea ...

... To illustrate using the "X" variable, first we find the deviation of each score from the mean. We have already determined that the mean of X in our example is 51.5. Therefore, we subtract the mean from each value of the X variable (Xi - mean of X). Next, we square each deviation (Xi - mean of X)2. [ ...
