The Relationships procedure contains a number of columns and uses various formulae:
Word 1: the first word in a pair, followed by Freq. (its frequency in the whole index).
Word 2: the other word in that pair, followed by Freq. (its frequency in the whole index). If you have computed "to right only", then Word 1 precedes Word 2.
Texts: the number of texts this pair was found in (there were 23 in the whole index).
Gap: the most typical distance between Word 1 and Word 2.
Joint: their joint frequency over the entire span (not just the joint frequency at the typical gap distance).
In line 2 of this display, SCIENTISTS occurs over 29,000 times in the whole index (based on US climate change news text), and it comes joint with CLIMATE over 3,000 times. This is shown in the status bar. The gap is 1 because scientists, in these data, typically comes 1 words away from climate. The pair climate * scientists comes in 168 texts. (This search was computed using the to right only setting mentioned above).
There is a big difference in the DeltaPA and DeltaPB scores for the pair climate * denier. That's because roughly 216 in 421 is a much bigger proportion than 216 in 136,000. Therefore in these data, denier is a better predictor of climate than climate is of denier.
As usual, the data can be sorted by clicking on the headers.
