tau3ordered: The partition of the Marcotorchino three-way index.
Description
When three categorical variables are symmetrically related, we can analyse the strength of
the association using the three-way Marcotorchino index.
The function chi3 partitions the Marcotorchino statistic using orthogonal polynomials
when, in CA3variants, we set the parameter ca3type = "ONSCA3".
Usage
tau3ordered(f3, digits = 3)
Value
The partition of the Marcotorchino index into three two-way non-symmetrical association terms and one
three-way association term. It also shows the polynomial componets of inertia, the
percentage of explained inertia, the degrees of freedom and p-value of each term of the partition.
Arguments
f3
The three-way contingency array given as an input parameter in CA3variants.
digits
The number of decimal digits. By default digits=3.
