chi-square, log likelihood, or log ratio, and p value.
The criterion for what counts as "outstanding" is based on the minimum probability value entered before the lists were compared. The smaller this probability value the fewer words in the display.
The words appear sorted according to how outstanding their frequencies of occurrence are. Those near the top are outstandingly frequent in your main word-list. At the end of the listing you'll find those which are outstandingly infrequent in the first text chosen: in other words, key in the second text.
This comparison is similar to the analysis of "key words" in the KeyWords program. The KeyWords analysis is slightly quicker and allows for batch processing.
