Switch documents between two groups to maximize chi-square value

Usage

switch_docs(m, indices, max_index, max_chisq)

Arguments

m: original dtm
indices: documents indices orderes by first CA axis coordinates
max_index: document index where the split is maximum
max_chisq: maximum chi-square value

Value

a list of two vectors indices1 and indices2, which contain the documents indices of each group after documents switching, and a chisq value, the new corresponding chi-square value after switching
