WebGeographically weighted regression (GWR) is a spatial analysis technique that takes non-stationary variables into consideration (e.g., climate; demographic factors; physical environment characteristics) and models the local relationships between these predictors and an outcome of interest. Description WebThe inverse lag operator L 1 simply shifts the series forward one time period, L 1X t = X t+1, whereL 1LX t = Xt. A lag polynomial a(L) is defined as a(L) = ¥ å j=0 a jL j, and so the lag polynomial applied to the time series Xt delivers a(L)Xt = å j=0 a jX t j = a 0Xt + a 1X t 1 + a 2X t 2 +. . . We also refer to a(L)Xt as a linear, time invariant filter of Xt. Definition 1.4.
