Struct VifResult 

pub struct VifResult {
    pub variable: String,
    pub vif: f64,
    pub rsquared: f64,
    pub interpretation: String,
}

Result of VIF (Variance Inflation Factor) calculation.

VIF measures how much the variance of an estimated regression coefficient increases due to multicollinearity among the predictors.

Fields

• variable - Name of the predictor variable
• vif - Variance Inflation Factor (VIF > 10 indicates high multicollinearity)
• rsquared - R-squared from regressing this predictor on all others
• interpretation - Human-readable interpretation of the VIF value

Example

let vif = VifResult {
    variable: "X1".to_string(),
    vif: 2.5,
    rsquared: 0.6,
    interpretation: "Low multicollinearity".to_string(),
};
assert_eq!(vif.variable, "X1");

Fields

variable: String

Name of the predictor variable

vif: f64

Variance Inflation Factor (VIF > 10 indicates high multicollinearity)

rsquared: f64

R-squared from regressing this predictor on all others

interpretation: String

Human-readable interpretation of the VIF value
