power analyses for mixed effects lmer models
...n show a stronger word
frequency effect. I have 50 words of varying frequency that I show to 30 men
and 30 women, who are supposed to decide as quickly as possible whether it's
a real word. So my data object would end up being 3000 lines long, and look
like this:
Subject Word Sex Frequency ReactionTime
s1 w1 M 23 2543
s1 w2 M 67 1438
s1 w3 M 1 8033
...
s60 w50 F 4 1099
I analyze this with
lmer(log(ReactionTime) ~ (Sex * Frequency) + (1|Subject) + (1|Word)
Does anyone know how I might do power analyses or compute effect sizes in
this kind of situation?
Thanks.
