In genetics, the coefficient of coincidence (c.o.c.) is a measure of interference in the formation of chromosomal crossovers during meiosis. It is generally the case that, if there is a crossover at one spot on a chromosome, this decreases the likelihood of a crossover in a nearby spot. [1] This is called interference.
Krippendorff's alpha coefficient, [1] named after academic Klaus Krippendorff, is a statistical measure of the agreement achieved when coding a set of units of analysis.. Since the 1970s, alpha has been used in content analysis where textual units are categorized by trained readers, in counseling and survey research where experts code open-ended interview data into analyzable terms, in ...
Coincidences involving the letter E, for example, are relatively likely. So when any two English texts are compared, the coincidence count will be higher than when an English text and a foreign-language text are used. This effect can be subtle. For example, similar languages will have a higher coincidence count than dissimilar languages.
Where d is the distance in map units, the Morgan Mapping Function states that the recombination frequency r can be expressed as =.This assumes that one crossover occurs, at most, in an interval between two loci, and that the probability of the occurrence of this crossover is proportional to the map length of the interval.
In statistics, probability theory and information theory, pointwise mutual information (PMI), [1] or point mutual information, is a measure of association.It compares the probability of two events occurring together to what this probability would be if the events were independent.
Some quite famous coincidences weren’t even mentioned in this list. For example, the one about the writer Mark Twain and the comet. He was born on November 30, 1835, when Halley’s comet came ...

Removing the coefficient might not be preferred by everyone. But we can at least move the coefficient out in front of the calculation so as to: 1. visually simplify the formula 2. make the calculation more efficient 3. highlight its role, make it more explicit 4. make it obvious how to normalize or de-normalize a result for quick conversions
