How to fix a broken experiment done in 3 blocks?
I have a DOE where I've blocked runs by month - I can run 4 runs/month, for a total of 12 runs over 3 months. Is there a way to salvage my design if 1 of the runs in a block fails due to outside circumstances unrelated to the DOE factors? For example, run number 4 in my 1st block of experiments had to be stopped half way through due to a raw material supplier issue, so that block only has 3 runs ...
