Description of options

Data = Name | #Number

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

Column = Name | #Number

Specifies the column in the matrix specified by Data for which join counts will be determined.

Lag = Connect | Distance

Specifies whether to describe lags for the join counts using distances or connections. The default is to use distances.

Connections = Name | #Number

When Lag = Connect, this specifies the binary matrix which specifies the connections among the data points.

Distances = Name | #Number

When Lag = Distance, this specifies the geographic distance matrix to be used to place data into specific lag classes.

DistClass = Name | #Number

When Lag = Distance, this specifies the details of the lag classes.

ExcludeLarge = Yes | No

When Lag = Distance, this specifies whether to calculate the correlation for the largest distance class.

IncludeAA = Yes | No

Specifies whether or not to include A vs. A contrasts as joins. The default is Yes. At least one of IncludeAA, IncludeAB and IncludeNotA must be used.

IncludeAB = Yes | No

Specifies whether or not to include A vs. B contrasts as joins. The default is Yes. At least one of IncludeAA, IncludeAB and IncludeNotA must be used.

IncludeNotA = Yes | No

Specifies whether or not to include A vs. Not A contrasts as joins. The default is Yes. At least one of IncludeAA, IncludeAB and IncludeNotA must be used.

AssumeReplace = Yes | No

Specifies whether to assume sampling with replacement. The default is No.

Weights = Binary | InvDist | InvDist2 | InvDist3

Specifies the weighting scheme to be used in the join counts. The default is binary weighting

Permute = Yes | No

Specifies whether or not to estimate significance using a permutation test. The default is Yes.

Permutations = Number

Specifies the number of permutations with which to perform a permutation test (if Permute = Yes). The default is 999; the minimum value is 49.

Save = Yes | No

Controls whether the output is saved into an independent matrix. The default is No.

SaveName = Name

When Save = Yes, this specifies the name of the output matrix. This name cannot be identical to the names of any other matrices already in memory.
