    }[]

    Minitab's unusual observations: R = large standardized residual (|r| > 2), X = high leverage (h > 3p/n).

    y: Float64Array

    • Predict at new rows (arrays of predictor values in names order, without the constant).

      Parameters

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

      Returns Prediction[]
