In contrast to the mean absolute percentage error, SMAPE has both a lower bound and an upper bound. Indeed, the formula above provides a result between 0% and 200%. Indeed, the formula above provides a result between 0% and 200%.
A Phred quality score is a measure of the quality of the identification of the nucleobases generated by automated DNA sequencing. [1] [2] It was originally developed for the computer program Phred to help in the automation of DNA sequencing in the Human Genome Project. Phred quality scores are assigned to each nucleotide base call in automated ...
Confusingly, sometimes when people refer to wMAPE they are talking about a different model in which the numerator and denominator of the wMAPE formula above are weighted again by another set of custom weights .
The coefficient of variation (CV) is defined as the ratio of the standard deviation to the mean , [1] It shows the extent of variability in relation to the mean of the population. The coefficient of variation should be computed only for data measured on scales that have a meaningful zero ( ratio scale) and hence allow relative comparison of two ...

Two basic conventions are in common use for some Arabic numerals: display segment A is optional for digit 6 (/), segment F for 7 (/), and segment D for 9 (/). Although EF could also be used to represent digit 1, this seems to be rarely done if ever.
In software development (and computer programming in general), code reuse, also called software reuse, is the use of existing software, or software knowledge, to build new software, [1] [2] : 7 following the reusability principles . Code reuse may be achieved by different ways depending on a complexity of a programming language chosen and range ...
