Struct ComparisonReport 

pub struct ComparisonReport {
    pub delta_elpd: f64,
    pub delta_elpd_se: f64,
    pub delta_aic_corrected: f64,
    pub rows_aligned: bool,
}

Result of comparing two fits on the same response: the paired predictive difference with its standard error plus the corrected-AIC gap. Both differences are oriented a − b: positive delta_elpd favours a, negative delta_aic_corrected favours a.

Fields

delta_elpd: f64

Σᵢ (elpd_aᵢ − elpd_bᵢ); positive favours a.

delta_elpd_se: f64

SE of delta_elpd from the pointwise paired differences, √(n · Var(elpd_aᵢ − elpd_bᵢ)).

delta_aic_corrected: f64

AIC_corrected(a) − AIC_corrected(b); negative favours a.

rows_aligned: bool

false when the two fits have a different number of observations and the paired predictive difference could not be formed; delta_elpd is then NaN and only the AIC gap is meaningful.
