virhevarianssi
Virhevarianssi, often translated as error variance or residual variance, is a key concept in statistics, particularly in the context of regression analysis and the analysis of variance (ANOVA). It represents the variability in the dependent variable that cannot be explained by the independent variables included in the model. In simpler terms, it's the part of the total variation that is due to random error, unmeasured factors, or inherent noise in the data.
In regression, the total variation in the dependent variable is typically partitioned into explained variation (due
The error variance is a crucial component for estimating other important statistical measures. For instance, it
