Struct ChannelStats 

Source 
pub struct ChannelStats {

Expand description

Welford online-variance statistics accumulator for one scalar channel.

Computes mean and variance incrementally without storing all samples.

Fields§

§count: u64

Number of samples observed.

§mean: f64

Running mean.

§m2: f64

Running M2 (sum of squared deviations) for Welford’s algorithm.

§min: f64

Minimum value seen.

§max: f64

Maximum value seen.
