mean square
Noun
Meaning
mean square (plural mean squares)
The average of the squares of a set of numbers.
Alternative names
mean-square
Examples
As a result, voltage for alternating current almost never refers to the voltage at a particular instant, but instead is the root mean square (RMS) voltage, which is a way of defining an effective voltage when calculating power (RMS voltage × RMS current).
Jitter can be quantified in the same terms as all time-varying signals, e.g., root mean square (RMS), or peak-to-peak displacement.
Estimating the parameters The most common choice in optimization of parameters is the root mean square criterion which is also called the autocorrelation criterion.
If rather the fields are described in terms of their root mean square (rms) values (which are each smaller by the factor ), then the correct average power flow is obtained without multiplication by 1/2.
It is common to determine curve shapes to minimize the mean square error, so it is appropriate that the goodness-of-fit calculation sums the squared errors.
Mathematically the radius of gyration is the root mean square distance of the object's parts from either its center of mass or a given axis, depending on the relevant application.
