“…Anselin (1988c) was one of the first to combine the two topics, giving rise to the well-known battery of tests of autocorrelation and heteroskedasticity; Anselin (1990) and Páez, Uchida, and Miyamoto (2001) continue along the same lines, adapting the Chow test to models with spatial dependence. Later, Brunsdon, Fotheringham, and Charlton (1998a), Pace and Lesage (2004), and López, Mur, and Angulo (2009) develop models where the mechanism of spatial dependence is specific for each point in space. These last three articles may be seen as a natural extension of the Locally Weighted Regressions algorithm, introduced by Cleveland (1979) and Cleveland and Devlin (1988) and subsequently developed by, among others, McMillen (1996), McMillen and McDonald (1997), Brunsdon, Fotheringham, and Charlton (1998b), and Páez, Uchida, and Miyamoto (2002a, 2002b).…”
