Specifies the data matrix containing columns of data from which to estimate the correlation.

Columns = All | {Name | #Number, Name | #Number, etc.}  

Specifies the columns for which correlations will be determined. All possible pair wise correlations will be calculated from the list. At least two columns must be specified. The default is to include all columns.

Distances = Name | #Number

Specifies the distance matrix from which to estimate spatial autocorrelation.

DistClass = Name | #Number

Specifies the distance classes for which to estimate spatial autocorrelation.

Dutilleul = Yes | No

Controls whether PASSaGE should perform Dutilleul’s exact solution for the test.
