[R-sig-ME] Distributional Assumption in lmer()

[Hedyeh Ahmadi]

Hello All,
I was wondering if there is a way to implement t-distribution assumption instead of family ="Gaussian" assumption in the lmer() function.

I am asking since I have been seeing heavy tails in my outcomes and it shows up in my residual diagnostic QQplot hence I think a t-distribution would be more appropriate compared to Normal distribution.

Any help would be greatly appreciated.

Best,
