Struct RandomInterceptParams 

Source 
pub struct RandomInterceptParams {
    pub lambda_max: f64,
    pub lambda_tol: f64,
    pub satterthwaite: bool,
}
Expand description

Tuning knobs for fit_random_intercept.

Fields§

§lambda_max: f64

Upper end of the bracket searched for the variance ratio.

§lambda_tol: f64

Convergence tolerance for the variance ratio.

§satterthwaite: bool

Compute Satterthwaite degrees of freedom. Turning this off leaves df at the residual value n - p and skips a numerical Hessian and one gradient per coefficient, which is worth doing when fitting at scale and the group count is large enough that the two agree anyway. An exhausted bracket still yields NaN regardless of this flag.

Implementations§

Source§

impl RandomInterceptParams

Source

pub fn new(lambda_max: f64, lambda_tol: f64, satterthwaite: bool) -> Self

§Params
  • lambda_max - Upper end of the variance-ratio bracket
  • lambda_tol - Convergence tolerance for the variance ratio
  • satterthwaite - Compute Satterthwaite degrees of freedom
§Returns

The parameter set.
