LSMeans Tests between Student's t vs. Tukey HSD

[#1]

Has anyone seen this result where Student's t letters are the same while Tukey HSD letters are different. I usually see visa versa. Any thought?

I would not perform any post hoc tests until I validated the assumptions of the model and addressed all the issues with the estimation.

• Did you notice the warnings in the report of the variance components?
• Did you notice that your model is over-specified and the fixed and random effects are confounded?
• Did you notice that one of the random effects is zeroed?
• How do you justify treating gender as a random effect?

I don't think that this analysis is quite ready for any post hoc tests.
