Root mean square fluctuation — The mean square fluctuation (MSF) is a measure of the deviation between the position of particle i and some reference position. MSF=frac{1}{T}sum {t j=1}^{T}(x i(t j) ilde{x} i)^2,where T is the time over which one wants to average, and ilde{x} i … Wikipedia
Mean squared error — In statistics, the mean squared error (MSE) of an estimator is one of many ways to quantify the difference between values implied by a kernel density estimator and the true values of the quantity being estimated. MSE is a risk function,… … Wikipedia
Square root of 5 — The square root of 5 is the positive real number that, when multiplied by itself, gives the prime number 5. This number appears in the formula for the golden ratio. It can be denoted in surd form as::sqrt{5}.It is an irrational algebraic number.… … Wikipedia
Square (algebra) — In algebra, the square of a number is that number multiplied by itself. To square a quantity is to multiply it by itself.Its notation is a superscripted 2 ; a number x squared is written as x ². Thus: If x is a positive real number, the value of… … Wikipedia
Square number — In mathematics, a square number, sometimes also called a perfect square, is an integer that can be written as the square of some other integer; in other words, it is the product of some integer with itself. So, for example, 9 is a square number,… … Wikipedia
