Hi,
I am wondering how AM2 (amplitude modulation) works when two simultaneous variables are used. When a trial (e.g., a word) has two ABI values (e.g., word length and word frequency), how does AM2 work? When there is one value, what I understand is that the effect of the variable is like a slope in a regression model. How about two (or more) regressors? Is the case similar to multiple regression?
Thanks in advance,
