Quantile LISA

Quantile LISA (2019) is quantile local spatial autocorrelation that applies local join count statistics to quantiles of a continuous variable by converting the continuous variable to a binary variable that takes the value of 1 for a specific quantile.

Arguments

Name	Type	Description
w	WeightResult	the WeightResult object created from weights function
k	Number	the total number of quantiles
quantile	Number	the index of which quantile is used in local join count statistics
val	Array	the numeric column that contains the binary values (e.g. 0 and 1) for LISA statistics
permutations	Number	the number of permutations for the LISA computation. Default: 999.
permutation_method	String	the permutation method used for the LISA computation. Options are 'complete', 'lookup'. Default: 'lookup'.
significance_cutoff	Number	the cutoff value for significance p-values to filter not-significant clusters. Default: 0.05.
seed	Number	the seed for random number generator used in LISA statistics. Default: 123456789.

Return

Type	Description
LisaResult	The LisaResult object contains the results of LISA computation: pvalues, clusters, lisa_values, neighbors, labels, colors
