Struct StatEllipse

Source

pub struct StatEllipse {
    pub level: f64,
    pub segments: usize,
}

Expand description

Confidence ellipse for a 2-D point cloud (analogous to R’s stat_ellipse).

Assumes a bivariate normal distribution: the ellipse is the covariance eigen-decomposition scaled by the chi-square quantile for level (df = 2). Emits segments + 1 boundary points forming a closed path per group.

Fields§

§level: f64

Confidence level in (0, 1). Default 0.95.

§segments: usize

Number of segments used to draw the ellipse. Default 51.
