[R] anova repeated measure
Dear R people, I'm new user of R and I'm trying to do a Anova with 3 different tests (intra subject), 6 times of measures (intra subject) and 3 groups (inter subject). I want to obtain an Huynh-Feldt epsilon on accuracy with: >anova(lm(acc.t1~gr.dem),test="Spherical") for test 1 # gr.dem is my group variable >anova(lm(acc.t2~gr.dem),test="Spherical") for test 2 >anova(lm(acc.t3~gr.dem),test="Spherical") for test 3 acc.t1, acc.t2 and acc.t3 was data frames with 6 columns each the results was something like this: Analysis of Variance Table Greenhouse-Geisser epsilon: 0.2746 Huynh-Feldt epsilon:0.2915 Df F num Df den Df Pr(>F) G-G Pr H-F Pr (Intercept) 1 7352.7017 6150 1.640e-182 6.894e-52 6.269e-55 gr.dem10.6222 61500.712300.511700.52064 Residuals25 And so what could I do with my epsilon? Previous aov() revealed me that there no effects of my groups but is my 6 times measures factor and my test factor were always significant?
