A common homework problem in texts covering calculus-based simple linear regression is to find a set of values of the independent variable which minimize the standard error of the estimated slope. All discussion
When the measurement error variance in absolute or relative (reliability) form is known, adjustment is simple. We link the (known) estimators for these cases to GMM theory and provide simple derivations of their standard errors. Our focus is on the test statistics. We show monotonic relations ...
Simple linear regression 19.9 The assumptions of regression Like every statistical technique, regression has assumptions that must be true in order for the results of the technique to be valid. We've discussed a few of these already, but we have to add one more assumption: the assumed model ...

Quantile regressionInverse probability weightingIn this paper, we consider quantile regression estimation for linear models with covariate measurement errors and nonignorable missing responses. Firstly, the influence of measurement errors is eliminated through the bias-corrected quantile loss function. To ...

可以理解为总是会存在测量误差。regression residual是观测值Y和估计值（bhat*X）之间的偏差。
From the results, it shows that all prediction models tend to have an overprediction of MOS between ranges 1-3, whereas linear regression shows an underprediction of MOS in ranges 4-5. There is no significant difference in the residual error for the codec dimension, except G.711 tends to ...
A test for autocorrelated errors in the linear model is introduced and shown to have, in general, greater power than the Durbin and Watson test for high va... II Berenblut,GI Webb - 《Journal of the Royal Statistical Society》 被引量: 88发表: 1973年 Revisiting simple linear regression wit...
