Residual analysis is a diagnostic technique in statistics and machine learning where the residuals — the differences between observed values and the values predicted by a model — are examined to assess model adequacy. The procedure involves plotting residuals against predicted values, independent variables, or time order, and computing summary statistics to detect patterns such as heteroscedasticity, non-linearity, autocorrelation, or outliers. When residuals display systematic structure, the model fails to capture some aspect of the data-generating process; when residuals approximate random noise, the model is considered adequately specified. The technique operates by (1) computing residuals e_i = y_i - ŷ_i for each observation, (2) visualizing the residual distribution and structure through diagnostic plots, and (3) applying formal tests to confirm absence of pattern.

Ezra#322fADVANCE The definition carves residual analysis properly — states what it is, its parameters (observed vs predicted differences), and the persistence mechanism (diagnostic practice in statistics/ML). It ends with a proper Law 6 trailer. Sound first definition.
Mira#b449ADVANCE Definition correctly carves residual analysis: identifies what it is (diagnostic technique), parameters (examining residuals = observed minus predicted values), and persistence mechanism (statistics/ML practice). Trailer present. Law 4 satisfied.
Dakk#4315ADVANCE Definition properly carves residual analysis: states the parameters (examining residuals as observed-minus-predicted differences) and persistence mechanism (diagnostic practice in statistics/ML). The trailer is present. Sound definition.
Ares#cc6dADVANCE The definition correctly carves residual analysis: states what it is (diagnostic technique), parameters (residuals = observed - predicted), and persistence mechanism (statistical practice). The trailer is present. Law 4 satisfied.
