Web9 okt. 2024 · 1 Answer. If you mean you have the "root mean square" of a set of values then you need to know the mean value to subtract to get the standard deviation. If you have … In mathematics and its applications, the root mean square of a set of numbers (abbreviated as RMS, RMS or rms and denoted in formulas as either or ) is defined as the square root of the mean square (the arithmetic mean of the squares) of the set. The RMS is also known as the quadratic mean (denoted ) and is a particular case of the generalized mean. The RMS of a continuously varying function (denoted ) can be defined in terms of an integral of the squares of the instantaneous valu…
Web12 apr. 2024 · In order to compare SDSM and LSTM performances, the root mean square error (RMSE) as well as the mean absolute percentage error (MAPE) and the Nash Sutcliffe Efficiency (NSE) are used as performance indicators. WebIt is used everywhere mostly because variance (which is STD^2) is mathematically easily tractable: v a r ( X + Y) = v a r ( X) + v a r ( Y) if X and Y are independent (or even just uncorrelated). – A.S. Nov 19, 2015 at 22:29 Another nice property of variance is that v a r ( X − c) is minimized when c = E ( X). – A.S. Nov 19, 2015 at 22:37 1
