Fisher's LSD was used for pair-wise comparisons of LSmeans to determine significant effects (p < 0.05) for the two pre-planned comparisons.

A short explanation of LSMEANS is given in handout # 2.1. SAS provides for comparison of LSMEANS by the PDIFF option which gives a table

You may specify only classification effects in the LSMEANS .. presents results of the BON, GABRIEL, SCHEFFE, SIDAK, SMM, T, and LSD op- tions as intervals

It is somewhat important to understand how SAS works (with LSMeans). Instead of using (If we used LSD, we would see Treatment 3 as being better). Another
Treatment means at each day, with least significant difference (LSD), and differences between means . The second LSMEANS statement computes means for
Note that changing to an LSD error comparison showed . means, standard errors and LSMeans plots for the Processor factor, the number of programs factor
They provided a lot of tests: LSD, Duncan, Tukey-Kramer, Bonferroni, the adjusted means like these produced by the LSMEANS statement.

For the “overall” basis, least squares means were calculated for each Treatment and separated using LSD pairwise t-tests (LSMEANS Treatment/DIFFS).

In SAS, we use the LSMEANS statement to produce the least-squares These tests are analogous to the LSD means separation method in the balanced case.
