autocorrelation function

Climate of a given year t has a large effect on ring width for the same year. It can also affect ring width for a number k of years. Therefore the width of the ring in year t-1 is statistically related to the ring width in the ring t. This effect is modeled as autocorrelation in ring width. (Fritts 1976)
