Simple Effects Analysis SPSS

[Talk Stats]

Hi,

I missed this weeks tutorial at my university on how to use SPSS for simple
effects analysis. I currently have a two-way factorial ANOVA. My first
variable has 2 levels. My second variable has 3 levels. My question to you
is, what is the syntax I would use to compare the 3 levels of the second
factor within eachother? I know I may have to use the MANOVA approach. I've
googled this a million times and I can't find a clear cut answer. Can
someone please please help.

I have been asked a question that I do not have an answer to here.  I
have checked all my various sources and have drawn a blank.  We
completed a study using a traditional conjoint model (full-information,
additive if it makes a difference).  A reviewer asked us to supply a
statement on beta (or power) in this approach.  Now I understand that we
can do so for analysis of the data post conjoint, and we could address
it as one would a general survey approach.  Is there a specific way to
evaluate power or beta for a conjoint model specifically?

TIA
Dale
