These methods depend on the spatial correlation model derived from the well known semivariogram function.
Is one of the most widely used global indicators for verifying the existence of spatial correlation.
The indices used in our study to identify the spatial correlation were the global Moran's indicators.

It was found that there is no specific spatial correlation for neonatal mortality in the Brazilian states R 0.002, p 0.48.
For each index and seasonal year, the Moran indices were calculated,as they are global measures of spatial correlation.
The spatial correlation between neighboring sites was calculated using the semi-variance?h, with the aid of the software GEOSTAT.
The null hypothesis for non-autocorrelation is that l=0, i.e.,the error term has no spatial correlation.
In which the estimates are obtained using spatial correlation between the levels of pollutant and by autocorrecting of the levels of this pollutant.
Ripley's K-function represents the spatial dependency of the process andis derived from the spatial correlation structure.
For this purpose, first the spatial correlation was investigated by a global(moran's i) and local(local moran's i) perspective.
As a final product Figure 6, we obtained the map information with the intersection of the two grids,where it was possible to observe a spatial correlation.
There is significant, butnot absolute, spatial correlation among these characteristics, making the delineation of ecoregions an imperfect science.
A way to bypass that trouble is to utilize a spatial approach in which it is possible to estimate and model the spatial correlation among the mistakes.
Currently researches using spatial correlation techniques showed activation of the medial prefrontal cortex(mpfc) on irony comprehension tasks.
In this study the Moran Global Index was used to verify the existence of spatial correlation in the default rate between the regions in the DF.
The existence of spatial correlation, the presence of clusters and critical areas of the event studied were analyzed using Moran's I Global and Local indices.
Sometime afterwardsbit was considered for normal distribution with an average of zero and variants, in other words,without considering the spatial correlation structure.
To test the hypothesis that there is a spatial correlation between the data, we used the Moran Index, which checks for spatial independence.
Global Moran coefficients for the mortality rates of the variables studied can be found in Table 1. The positive spatial correlation presented in 2007 may be observed in Table 1.
