linearity

lin·e·ar·i·ty

(lin'ē-ar'ĭ-tē),
A relationship between two quantities whereby a change in one causes a directly proportional change in the other.
[L. linearis, linear, fr. linea, line]

linearity

[lin′ē·er′itē]
the principle that the density of a radiographic exposure is determined by the product of the current and the exposure time.

linearity

Statistics A straight line relation between 2 quantities, where when a value 'X' is ↑ or ↓, 'Y' is proportionately ↑ or ↓; linearity assumes that the relation between X and Y–abscissa and ordinate can be summarized in a straight line, known as a least-squares regression method

linearity

the characteristic of being a straight line. If one variable is a linear function of another, a graph prepared by plotting one against the other will be a straight line.

Linearity, as defined above, is not required by CLIA but is recommended and is considered Good Laboratory Practice.
Saikkonen and Luukkonen (1988) suggests a linearity test against an ESTAR model by approximating equation (1) via first order Taylor series with respect to equation (3) around g = 0.
Taking as our starting point Kaplan's premise that there exists a logical principle underpinning the discursive organisation of every language and that such a principle is rooted in Aristotle's logic and Galileo's systematisation, which the idea of linearity underlies (1980: 402), we try to prove the following null hypotheses: 1.
If the data are too imprecise, then no final determination of linearity is given.
We evaluated all data using the polynomial evaluation method for linearity, as described by Kroll and co-workers (1,2).
80 MHz to 220 MHz have the following features: any frequency within the operating range with six decimal places of accuracy; a wide pull range, up to [+ or -]1600 PPM (pull ranges up to [+ or -]200 PPM are also available); linearity of Less than 1 percent; tuning slope (Kv) consistency; and frequency stability as low as [+ or -]10 PPM.
In applications where optimum linearity is not essential, the practical operating range may extend well beyond the specified nominal linear range.
Besides having an impressive basic performance, its timing linearity is improved even further with the use of a unique built-in hardware correction circuit and auto-calibration software scheme.
is broadening its optoelectronics portfolio with the introduction of six new Automotive Grade, high-speed silicon PIN photodiodes that feature excellent photoresponse linearity for small signal detection.
The A1c-Cellular[R] Linearity product is commercially-available Hemoglobin A1c (HbA1c) linearity/calibration verification material with intact red blood cells.
