Chapter 7 RCBD in GLM and MIXED SUMMARY: Data was analyzed using GLM, VARCOMP, and MIXED to see differences and look at what these procedures do when handling different kinds of data. In proc varcomp , the method options include Type1 (or method of moments), mle (maximum likelihood), reml (restricted maximum likelihood), and mivque0 (minimum variance quadratic estimator). Mivque0 is the default fro varcomp. Varcomp assumes all factors are random unless specified otherwise. Factors MUST always be listed before random effects. In mixed , only fixed effects go in the model statement. The random effects go in the random statement. SAS Procedures, Statements and Options: goptions rotate = hsize = 7 in vsize = 5 in proc gplot data = ____ plot proc glm data = ____ class model ___ / ss3 random ___/ test lsmeans ___/ tdiff pdiff stderr Proc varcomp data = ____ method = reml class model ___ /fixed = 1 proc mixed data = ___ cl class model random lsmeans pdiff

Chapter 7 Answers to questions 13. Yes, there appears to be a difference. Thrust is varying with levels of mix but it is not very clear if the means vary because data is so spread out due to block effects.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
