    aic: number
    bic: number
    coefficients: LifeCoefficient[]

    Regression coefficients on the (log) location: intercept first.

    iterations: number
    logLik: number
    n: number
    nFailures: number
    residuals: { coxSnell: Float64Array; standardized: Float64Array }

    Standardized residuals (on the location-scale) and Cox–Snell residuals.

    scale: { ci: [number, number]; estimate: number; se: number }

    Scale σ (Weibull shape = 1/σ) with SE and CI.

    shape?: number
    test: "regression with life data"

    • Percentiles at a covariate setting: t_p with delta-method CI.

      Parameters

      • x: ArrayLike<number>
      • Optionaloptions: { confidence?: number }

      Returns { ci: [number, number]; p: number; se: number; time: number }

    • Survival probability at a time and covariate setting.

      Parameters
