Mean squared error - Wikipedia

https://en.wikipedia.org/wiki/Mean_squared_error

WEBIn statistics, the mean squared error (MSE) or mean squared deviation (MSD) of an estimator (of a procedure for estimating an unobserved quantity) measures the average of the squares of the errors—that is, the average squared difference between the estimated values and the actual value.

WEBJan 18, 2024 · The equation for MSE is the following: MSE = (1/n) * Σ i (x i - y i)², where i runs from 1 to n. If we ignore the 1/n factor in front of the sum, we arrive at the formula for SSE: SSE = Σ i (x i - y i)², where i runs from 1 to n. In other words, the relationship between SSE and MSE is the following: MSE = SSE / n.

WEBOne of the most common measures is Mean Square Error, or MSE, which is defined as. MSE(θ) = Eθ[(δ(X) − θ)2] Estimators δ(X) that have small MSE are considered good because their expected distance from θ is small (if the squared error is small then the actual distance will be small as well).
