Regression through the origin variance of estimator. org When the regression of Y on X is linear, the line doesn't need to always pass through the origin. An example of using regression is given. This article describes situations in which regres-sion through the origin is appropriate, derives the normal equation for such a regression and explains the controversy r Overview This lesson discusses when and how to use regression estimation. Under such conditions, it is more appropriate to use the regression type estimator to estimate the population means. Having prior knowledge that a regression model passes through the origin modifies the estimation procedure somewhat. See full list on statology. This is due to the fact that the estimation of the intercept is no longer required since its value is known. . In the ratio method, the conventional estimator sample mean y was improved by multiplying it by a factor This is called regression through the origin. Then we compare the regression estimate by simply using the sample mean, not taking advantage of the auxiliary information. All statistical packages allow you to fit this model, and it is useful at times - but one must interpret the results with care.
