it is very simple, each average using certain number of days, 7 or 14 has to have a start date, ie the day you first designated as day minus 7 or day minus 14, the day you went back to start averaging 7 or 14 days,if you picked april 21 to start, going back 7 or 14 days gives you the 14th or 7th as the day from which you first started your averging and then you move forward to the 22nd, then 23rd, etc in getting your 7 or 14 day averages.
If we want the 7-day rolling average for April 21st, we will start with April 21st, then move back to the 20th, 19th, 18th, 17th, 16th, and 15th. For a rolling 7-day average on a given day, we use the given day and the 6 days before it.
guess you are messing with me, all i really asked is what date, ie april 14, march 27, what did you use as your start date so you can compare 7 and 14 day averages now to then, you had to have said, ok, i am going to go back to april 1st to start my comparisons.
It’s a rolling average, so why does start date matter? Obviously if you are doing a 7 day average, you need 7 days worth of data before you can really start averaging. Beyond that, the rolling average is a line along a continuum. Probably most useful for looking at peaks and troughs and smoothing out some of the noise in reporting (i.e. 1 day spike followed by a quiet reporting day, 7 day averages smooth that nonsense out).
god, all i asked for was what date you started comparing the averages too, are you comparing them to mid july and 65,000-70,000 daily and say we are doing better, are you comparing to mid march and 30,000 and say we are doing worse? i did not ask for the 7 secret herbs and spices or the formula for coca-cola for gods sake.
You can compare them to any period that you want. We had zero cases from 10/2 to 10/8 in 2019. The 7 day moving average allows an apples-to-apples comparison of any day, as it eliminates weekly cycles. The issue is the question that you want to ask.
Wasn't he was just comparing the September 12th 7day average to the most recent? Not sure what is confusing here....

You can compare any dates you want to compare. I'm not sure what that has to do with how 7-day rolling averages are calculated.
Tinker cliffs near Roanoke. Got a go gators on the way up. The leaves haven’t turned yet but they have lost their color.
It's nearly universal; the anti-mask, just the flu crowd can't grasp simple metrics, but they should be believed over those ivory tower grant whores.
It's possible the virus "loses steam" It's also possible that in the future, letting our guard down could lead to far worse numbers given how easily and quickly this virus has spread. Though I think we've got a great handle on treatment protocols in hospitals given the knowledge gained over the past seven months and this has likely led to thousands of lives being saved. FWIW, we've already been through two waves, hitting the second valley on Sep 8 (daily)/Sep 12 (7-day moving average) and are now in the early weeks of a third wave. *Data obtained from the Covid Tracking Project
