lsmeans one side inference

[mona4u]

I'm using Glimmix and I was trying to peerform one side inference test for the lower limit 

I'm wondering what is the right option to use 

LSmeans strata / diff=control('A') alpha=0.05 cl ;

See the one-sided section of this note. As mentioned there, when the test statistic is normally distributed you can simply halve the p-value if the observed statistic value satisfies the alternative hypothesis.

You need to use either the CONTROLL or CONTROLU difftype to get one-sided tests and confidence intervals.  Check the LSMEANS documentation in the Shared Concepts section of the documentation.
