This function computes the Generalized Wald-type test statistic (Wilson and Koehler, 1984) and corresponding p-value to assess whether the sample RAD probability-means from multiple populations are same or different. The statistics assumes that a common RAD probability-mean vector for comparison under the null hypothesis is unknown.
A list where each element is a matrix of taxonomic counts(columns) for each sample(rows).
Note: The matrices in
group.data must contain the same taxa, in the same order.
A list containing the Generalized Wald-type statistics and p-value.
