the minimum expected cell frequency Pearson's X^2 test requires some minimum frequency per cell to avoid an inflated false positive rate. This function will merge cells with the lowest frequency counts until all the counts are above the minimum threshold. Cells that have been merged are filled with NAs. The resulting tables and number of merged cells is returned. |
