peer agreement (net): +2periods staggered by one year Explanation: (Phase-shifting is applied to waves, isn't it?) I think the word "staggered" would serve. "Overlapping periods" is commonly found in relation to moving averages, but of course the three-year periods don't overlap by one year; they overlap by two, and you would have to redraft with some care in order to use that. I think this would be preferable. This example is about investments, not death rates, but the principle is the same: "In order to smooth things out I used 24 28-year periods, staggered by one month" http://www.efficientfrontier.com/ef/100/rebal100.htm As you can see from the following table, the periods are Jan-69 to Dec-96, Feb-69 to Jan-97, etc.: analogous to what you're dealing with. Another example; this ones' about ECG: "Figure 1 shows the mean (90% CI) time course of change in QTcF from baseline (ΔQTcF) during sequential iterations of 30 seconds measurements staggered every 5 seconds over 3 minutes for three episode of standing over 8 hours for the pooled group." http://www.icardiac.com/portals/0/pdfs/standingresponse_foss... -------------------------------------------------- Note added at 1 hr (2015-12-10 11:02:10 GMT) -------------------------------------------------- Yes, "periods time-shifted by one year" would work too, or perhaps even just "shifted by one year"; but not "phase-shifted", I think. No cases of that in statistical analysis, as far as I can tell. But "periods staggered by" is actually more common, for what that's worth; here's another: "Looking at all rolling 10-year-periods staggered by a month, starting in January, 1929, the worst decade returned minus 32.9%" http://www.barrons.com/articles/SB103619423047559951 |

| Reference: 3-year moving/rolling average shifted forward (right) by one year Reference information: In statistics, a moving average (rolling average or running average) is a calculation to analyze data points by creating series of averages of different subsets of the full data set. It is also called a moving mean (MM)[1] or rolling mean and is a type of finite impulse response filter. Variations include: simple, and cumulative, or weighted forms (described below). Given a series of numbers and a fixed subset size, the first element of the moving average is obtained by taking the average of the initial fixed subset of the number series. Then the subset is modified by ****"shifting forward"*****; that is, excluding the first number of the series and including the next number following the original subset in the series. This creates a new subset of numbers, which is averaged. This process is repeated over the entire data series. The plot line connecting all the (fixed) averages is the moving average. A moving average is a set of numbers, each of which is the average of the corresponding subset of a larger set of datum points. A moving average may also use unequal weights for each datum value in the subset to emphasize particular values in the subset. https://en.wikipedia.org/wiki/Moving_average This ref.
