Glossary Term
In statistical inference procedures (hypothesis tests and confidence intervals), nonparametric procedures are those that are relatively free of assumptions about population parameters.
Glossary Term
The probability that a test will produce a true negative result when used on non-effected subjects as compared to a reference or "gold standard". The specificity of a test can be determined by calculating: number of true negative results divided by the sum of true negative results plus number of false positive results.
Glossary Term
A non-target amplification built into a reaction to prove the assay chemistry worked even when the sample is negative. It helps distinguish a true negative from inhibition or setup failure, which matters when interpreting single-target assays on difficult matrices.
Glossary Term
Non-coding, intervening sequences of DNA that are transcribed, but are removed from within the primary gene transcript and rapidly degraded during maturation of messenger RNA.
Glossary Term
A nonparametric test for finding if three or more independent samples come from populations having the same distribution. It is a nonparametric version of ANOVA.
Glossary Term
A molecule of RNA 200-17000 nucleotides in length that is transcribed by non-protein coding areas of DNA. These ribonucleotides may play a role in a variety of biological processes.
Glossary Term
Required or expected data that is not present, which may be due to non-completion or corruption.
