Dear listers,
I am stuck with the experiment design of my dissertation. My experiment
would like to investigate the influences of different factors of stimuli
on the subject's response (each factor is a continuous variable), and
further build a regression model for these relations. My questions are:
1. It seems that no experiment-design issues related to Regression
Analysis are discussed in the usual statistics textbook. Why? Does it
mean one needn't consider the experiment design if he uses Regression
Analysis to analyze his data?
2. Due to the measure of the dependent variable is the participants'
subjective responses, to remove unrelated subject-specific variables, I
am considering to employ a within-subject design. But there seems no
statistical packages ready for dealing with within-subject design of
Regression Analysis?
Suppose a design in which each of the n subjects gives rise to a Y
observation under each of c different conditions, then a total of N=ncY
observations could be obtained. How can I use Regression Analysis to
analyze these observations?
Thanks for your help.
