Autocorrelation




0 Flares Twitter 0 Facebook 0 0 Flares ×

A correlation between values of a time series and values of the same time series shifted backwards or forwards by a fixed amount, called a lag. A typical example would be a correlation between a migraine patient's daily ratings of headache severity with the ratings one day earlier, each rating being paired with the one given on the previous day. In this case, the rating on the first day is paired with the rating on the second day, the rating on the second day with the rating on the third day, and so on. This is called the firstorder autocorrelation, and it tends to be positive if score t tends to be predictive of score t + 1. The autocorrelation of scores t with scores t + 2 is the second-order autocorrelation, and so on. See also autoregression, correlogram.

[From Greek autos self + English correlation].
