Result of Cook’s distance analysis.

Cook’s distance measures how much each observation influences the regression model. Unlike hypothesis tests, this is an influence measure - not a test with p-values.

Fields

test_name: String

Name of the test

distances: Vec<f64>

Cook’s distance for each observation (one per observation)

p: usize

Number of parameters (including intercept)

mse: f64

Mean squared error of the model

threshold_4_over_n: f64

Common threshold: 4/n (observations above this are potentially influential)

threshold_4_over_df: f64

Conservative threshold: 4/(n-p-1)

threshold_1: f64

Absolute threshold: D_i > 1 indicates high influence

influential_4_over_n: Vec<usize>

Indices of observations exceeding 4/n threshold

influential_4_over_df: Vec<usize>

Indices of observations exceeding conservative threshold

influential_1: Vec<usize>

Indices of observations exceeding D_i > 1 threshold

interpretation: String

Interpretation of results

guidance: String

Guidance for handling influential observations
