WR 1) Using the contents panel on the left (the search field is unreliable), find the syntax pages for the GLM procedure and answer the following questions.

            - What are all the multiple comparison ADJUSTments available in an LSMEANS statement?

            - What option do you use to NOT include the results of LSMEANS in the output?

            - What option do you use to include a t-test to test each hypothesis that there is no difference between each pair of means?

Explanation / Answer

Multiple effects can be specified in one LSMEANS statement, or multiple LSMEANS statements can be used, but they must all appear after the MODEL statement. For example:
proc glm;
class A B;
model Y=A B A*B;
lsmeans A B A*B;
run;
LS-means are displayed for each level of the A, B, and A*B effects.
You can specify the following options in the LSMEANS statement after a slash (/):
ADJUST=BON
ADJUST=DUNNETT
ADJUST=NELSON
ADJUST=SCHEFFE
ADJUST=SIDAK
ADJUST=SIMULATE <(simoptions)>
ADJUST=SMM | GT2
ADJUST=TUKEY
ADJUST=T

b) Use NOPRINT

c) use pdiff = all that gives differences of all pairs

lsmeans Treatment / pdiff=All;
