Expand description

Result of a paired significance test between two systems (very rough p-value approximation).

Fields§

§mean_a: f64

System A mean score.

§mean_b: f64

System B mean score.

§difference: f64

Difference (A - B).

§std_error: f64

Standard error of the difference.

§t_statistic: f64

t-statistic.

§p_value: f64

p-value (two-tailed, approximate).

§n: usize

Number of samples.

§significant_05: bool

Significant at p < 0.05.

§significant_01: bool

Significant at p < 0.01.
