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.
It introduces a parameter C, representing the coefficient of coincidence, and sets it equal to 2r. For loci which are strongly linked, interference is strong; otherwise, interference decreases towards zero. [5] Interference declines according to the linear function i = 1 - 2r. [8]
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 ...

A coincidence is a remarkable concurrence of events or circumstances that have no apparent causal connection with one another. [2] The perception of remarkable coincidences may lead to supernatural , occult , or paranormal claims, or it may lead to belief in fatalism , which is a doctrine that events will happen in the exact manner of a ...
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 ...

The concordance correlation coefficient is nearly identical to some of the measures called intra-class correlations.Comparisons of the concordance correlation coefficient with an "ordinary" intraclass correlation on different data sets found only small differences between the two correlations, in one case on the third decimal.
