C ratio; R std is the measured ratio for the standard; R pb is the measured ratio for the process blank, and R mb is the measured ratio for the machine blank. The next step, to correct for fractionation, can be done using either the 14 C / 12 C ratio or the 14 C / 13 C ratio, and also depends on which of the two possible standards was measured ...
Discrepancies began to be noted between measured ages and known historical dates for artefacts, and it became clear that a correction would need to be applied to radiocarbon ages to obtain calendar dates. [2] Uncalibrated dates may be stated as "radiocarbon years ago", abbreviated " 14 C ya". [3] The term Before Present (BP) is established for ...
The ratio of width to height of standard-definition television. In mathematics, a ratio (/ ˈ r eɪ ʃ (i) oʊ /) shows how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six (that is, 8:6, which is equivalent to the ratio 4:3).
Your debt-to-income ratio (DTI) is your total monthly debt payments divided by your total gross monthly income. It helps lenders determine your approval odds and the likelihood of you being able ...
The ratio estimator is a statistical estimator for the ratio of means of two random variables.

The ratio estimates are asymmetrical and symmetrical tests such as the t test should not be used to generate confidence intervals.

For example, on a plot axis showing log 2 fold changes, an 8-fold increase will be displayed at an axis value of 3 (since 2 3 = 8). However, there is no mathematical reason to only use logarithm to base 2, and due to many discrepancies in describing the log 2 fold changes in gene/protein expression, a new term "loget" has been proposed.
