I'm not sure I quite understand but I have the feeling I disagree with
what you are saying. The reason I don't understand is that it sounds
like if you buy the machine you get specific software. Therefore you
are not able to separate the effects of machine and software. I would
think you can not run one company's software on another company's
machine. But in your schematic of the design, you have software crossed
with machine (all softwares used on all machines), not nested, which
suggests you could run company A's software on company B's machine? If
one is not able to uncouple software from machine, which seems likely,
then really you just have a simple one-way ANOVA for any given measure,
where the replicate in a cell is subject? That is, you are comparing
four ways of getting you measure, person, machinesoftware1,
machinesoftware2, and machinesoftware3. Since you have 30 measures you
might consider a oneway MANOVA. Apologies if I have completely lost the
thread of what you intended to convey.
