In geometry, a locus (plural: loci) (Latin word for "place", "location") is a set of all points (commonly, a line, a line segment, a curve or a surface), whose location satisfies or is determined by one or more specified conditions.

relating to or expressed in terms of a parameter or parameters.

STATISTICS

assuming the value of a parameter for the purpose of analysis.

"variables with normal distribution were compared by means of parametric tests"

ELECTRONICS

relating to or denoting a process in which amplification or frequency conversion is obtained using a device modulated by a pumping frequency, which enables power to be transferred from the pumping frequency to the signal.
