Struct RandomEffect 

pub struct RandomEffect { /* private fields */ }

One random-effect term: a grouping factor plus the columns whose coefficients vary randomly across its groups.

• A random intercept for a factor is RandomEffect::intercept (a single column of ones).
• A random slope (with intercept) passes a design with an intercept column and the slope covariate via RandomEffect::new; each group then gets its own correlated (intercept, slope) pair, ~ N(0, Σ).

Supplying several terms with different grouping factors gives a crossed / nested model.

Implementations

impl RandomEffect

pub fn intercept(groups: &[usize]) -> Self

A random intercept for the factor whose per-observation labels are groups (arbitrary integers).

pub fn new(groups: &[usize], z: Array2<f64>) -> Self

A general random-effect term: groups labels and a per-observation design z (n × k) whose k columns have group-varying coefficients. Include a column of ones for a random intercept alongside random slopes.
