How to get all contrast results after mixed?
I used
mixed pme i.level2_enc || subject:,mle
to conduct a mixed effect model of pme ~ level2. Here my level2 has five categories, control, icon, HAS, HS, SW. After mixed, I tried using
contrast ar.level2_enc
to get all the comparisons, i.e. control vs SW, control vs HS, HAS vs SW, etc. However, I only get comprisons of following,
--------------------------------------------------------------------
| Contrast Std. Err. [95% Conf. Interval]
-------------------+------------------------------------------------
pme |
level2_enc |
(HS vs HAS) | -.1800729 .0815511 -.3399101 -.0202357
(SW vs HS) | .0470452 .0817447 -.1131715 .2072618
(control vs SW) | -.5816169 .1559947 -.8873608 -.275873
(icon vs control) | .6312981 .1560289 .3254871 .937109
--------------------------------------------------------------------
I checked the help contrast, and used contrast r.level2_enc and contrast i.level2_enc, but they did not give me all the comparisons.
