Least Square Elimination (LSE) cannot be applied to GLM models. Answer-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. Answer-True - the least squares estimates 
are BLUE (Best Linear Unbiased Estimates) in multiple linear regression
