We’ll get to that later?  But how … we’ll get to that later!  But anyway, so how can we compare characteristics between, say,  good Anton in good vs. bad dimensions or bad Anton in bad vs. good dimensions? Well, we might try employing the Wilcoxon signed-rank test or the paired t-test.  And there you have it!  But again, how can the same alter be in different worlds?  Well …
