Struct Prior 

pub struct Prior {
    pub mean: f32,
    pub variance: f32,
    pub reason: String,
}

Prior distribution for an axis.

Fields

mean: f32

Prior mean (expected value before observation).

variance: f32

Prior variance (uncertainty before observation).

reason: String

Human-readable reason for this prior.
