We tested the presence of spatial autocorrelation in the model residuals using spline correlograms (37) and we used the approach of Crase et al.
The four quadrants in the graph provide a classification of four types of spatial autocorrelation: high-high (Q1), low-low (Q2), for positive spatial autocorrelation; high-low (Q3) and low-high (Q4), for negative spatial autocorrelation.
we also estimated our model using the spatial auto-regressive (SAR) model with allowance for spatial autocorrelation in the error term.
In addition, we explore whether the spatial autocorrelation (Koenig and Knops, 1998; Overmars et al.
The spatial dependence of home bias between two trading countries with cultural, economic and geographical distances would likely yield spatial autocorrelation problems in the estimation of the home bias model (2).
Moran's I spatial autocorrelation analysis indicated that NDVI was a clustered variable in most blocks.
On a complementary level, a spatial autocorrelation study is carried out in order determine whether or not the geographical proximity of countries has any bearing on similar fiscal effort.
The global Moran's I index was used to estimate the strength of the global spatial autocorrelation of average leprosy case detection rate in this study.
To test whether these models were affected by spatial autocorrelation of residuals (Griffith 1987; Kissling and Carl 2008), we used the global Moran's I statistic.
Spatial autocorrelation is characterized by a correlation in a signal among nearby locations in space (Li.
