Least Square Elimination (LSE) cannot be applied to GLM models. - False - it is applicable but does not use data distribution information fully. In multiple linear regression with idd and equal variance, the least squares estimation of regression coefficients are always unbiased. - True - the least squares estimates are BLUE (Best Linear Unbiased Estimates) in multiple linear regression. Maximum Likelihood Estimation is not applicable for simple linear regression and multiple linear regres...

Regression Estimator Properties - Unbiasedness: This is the property that the expectation of the estimator is exactly the true parameter. What this means is that Beta_1_hat is an unbiased estimator for Beta_1 Model Parameter Interpretation - a positive value for Beta_1, then that's consistent with a direct relationship between the predicting variable X and the response variable Y Regression Analysis - Regression analysis is a simple way to investigate the relationship between 2 or more va...
