WebMar 26, 2016 · An autocorrelation plot shows the value of the autocorrelation function (acf) on the vertical axis. It can range from –1 to 1. The horizontal axis of an autocorrelation plot shows the size of the lag between the elements of the time series. For example, the autocorrelation with lag 2 is the correlation between the time series elements and the ...

Detecting Leaders from Correlated Time Series
WebJan 28, 2015 · To begin with, we’ll create two completely random time series. Each is simply a list of 100 random numbers between -1 and +1, treated as a time series. The first time is 0, then 1, etc., on up to 99. We’ll call one series Y1 (the Dow-Jones average over time) and the other Y2 (the number of Jennifer Lawrence mentions). WebApr 1, 2010 · An efficient algorithm is proposed which is able to track the lagged correlation and compute the leaders incrementally, while still achieving good accuracy, and the … WebSep 1, 2016 · Lag correlation between two time series is the correlation shifted in time relative to one another. Existing work focuses on two computation models, landmark (where the lag correlation is computed over the entire stream) and sliding window (where the lag correlation is computed over the current window). However, these models may suffer … cummins rocky mountain tucson az
