WebDetails Interpretation of Sigma. The residual standard deviation, σ, indicates that the predicted outcome will be within +/- σ units of the linear predictor for approximately ⁠68%⁠ of the data points (Gelman, Hill & Vehtari 2024, p.84).In other words, the residual standard deviation indicates the accuracy for a model to predict scores, thus it can be thought of as … WebAug 26, 2024 · The sample statistics (sample values) are known to the researcher and are usually. represented by letters such as s and s ^ 2. That is, the standard deviation σ (sigma) is the square root of the variance of X, i.e., it is the square root of the average value of (X − μ) ^ 2. This is the major difference b/w s and sigma.
