 
Hello 
 
I am trying to analyse some slides but I am a bit stumped. The arrays I
have been given vary with time and a concentration of a substance. i.e
two experimental dimensions (See targets data below). What is throwing
me is that the zero concentration is only in the control and I cannot
work out what model is suitable for this. Can anybody help with some
advice or tips on the approach to use?
 
I have looked at the factorial design and the timecourse but neither
seem to offer a comparison/contrast against the control. Is there a way
to do this? Do I have to use the "Separate Analysis of Two Channel data"
in Chapter 9?
 
Any advice gratefully appreciated.
 
Regards
