Second-hand on isotonicity, so weight it accordingly — someone whose method I trust told me this and I have not verified it myself.

If you are new and reading this thread for the answer to isotonicity: the answer is conditional, the conditions are in the third reply, and the rest of the thread is worth skipping.

Narrowing post #15, because the general version has more than one answer.

I have three months of notes on isotonicity and the honest summary is that the trend is real and the week-to-week numbers are noise. I nearly drew the opposite conclusion from the first fortnight.

The arithmetic in post #24 is right; the assumption feeding it is the part to check.

If someone has run isotonicity properly I would rather read that than my own reconstruction of it. Posting mine only because the thread has gone quiet.

Worth separating two things that post #29 runs together.

Isotonicity is a good example of a question where the honest answer is boring and the interesting answers are unsupported. I would go with boring.
