Least Square Elimination (LSE) cannot be applied to GLM models. - ANS 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. - ANS 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 l...

Question 1 The first few questions have to do with the parallel tests that we use when we DO have an adequately large sample size. They will be followed by questions where the sample size is small so nonparametric tests must be used. What is the name of the test where we compare one group of students who get a new reading curriculum to another who got the old curriculum. Assume n is 40 for both classrooms. Selected Answer: T­test for two means Answers: Matched pairs t­test Single mean t...
