WebFeb 10, 2024 · The formula to find the root mean square error, more commonly referred to as RMSE, is as follows: RMSE = √ [ Σ (Pi – Oi)2 / n ] where: Σ is a fancy symbol that means “sum”. Pi is the predicted value for the ith observation in the dataset. Oi is the observed value for the ith observation in the dataset. The RMS value of a set of values (or a continuous-time waveform) is the square root of the arithmetic mean of the squares of the values, or the square of the function that defines the continuous waveform. In physics, the RMS current value can also be defined as the "value of the direct current that dissipates the … See more In mathematics and its applications, the root mean square of a set of numbers $${\displaystyle x_{i}}$$ (abbreviated as RMS, RMS or rms and denoted in formulas as either $${\displaystyle x_{\mathrm {RMS} }}$$ See more In electrical engineering Voltage A special case of RMS of waveform combinations is: where Average electrical … See more If $${\displaystyle {\bar {x}}}$$ is the arithmetic mean and $${\displaystyle \sigma _{x}}$$ is the standard deviation of a population or a waveform, then: See more • A case for why RMS is a misnomer when applied to audio power • A Java applet on learning RMS See more The RMS can be computed in the frequency domain, using Parseval's theorem.
