Calculates local correlations based on nodes

Gives the node local Moran-I, Getis-Gstar or Geary-c correlations

NodeLocalCorrelation(obj, dep_type = "moran", intensity)

## S3 method for class 'intensitynet'
NodeLocalCorrelation(obj, dep_type = c("moran", "getis", "geary"), intensity)

Arguments

• obj: intensitynet object
• dep_type: 'moran', 'getis' or 'geary'. Type of local correlation to be computed (Moran-i, Getis-Gstar, Geary-c), default = 'moran'.
• intensity: vector containing the values to calculate the specified correlation for each node in the network.

Returns

a vector containing two values. The first value is a vector with the specified local correlations for each node. The second values is the given intensitynet class object but with the correlations added to the node attributes of its network.

Examples

## Not run:

data("und_intnet_chicago")
g <- und_intnet_chicago$graph
data_moran <- NodeLocalCorrelation(und_intnet_chicago, 
                                   dep_type = 'moran', 
                                   intensity = igraph::vertex_attr(g)$intensity)
moran_i <- data_moran$correlation
intnet <- data_moran$intnet
