Question

I have a one between factor (OdorGender) and with one within factor (Distinct), thus I'm trying to conduct a two way, mixed design anova.

So in my experiment, A group of people had experiment with FemaleOdor, and the other group had their experiment with MaleOdor.

Their task was to remember the certain stimuli while smelling the odor, and there were 5 distinct stimuli.

So each participants had all 5 distincts in their experiment.

I have a question on the two way ANOVA interaction (mixed design anova) in R.

I'm trying to use

lmer ??? or nlme?? what is the code..?

is there any other way to use R and do mixed design anova analysis?

And, how do I interpret the data of mixed design anova analysis??

Also, what happens if I add "NoOdor" group to the analysis? so then, I will have group of people who dealt with FemaleOdor, MaleOdor, and NoOdor.

I need explanation...

HELP!!

Explanation / Answer

There is no data given in the question , however a sample code for the 2 way anova R analysis is as follows

Please note that you have to update this code based on the data

fm1 <- nlme(dependent variable ~ SSasymp(independent variable, Asym, R0, lrc),
data = yourdata,
fixed = Asym + R0 + lrc ~ 1,
random = Asym ~ 1,
start = c(Asym = 103, R0 = -8.5, lrc = -3.3))
summary(fm1)

without data it is difficult to provide an interpretation
