Interface Gaussian

public interface Gaussian
The response variable is of Gaussian (normal) distribution. This family is used for ordinary linear regression and Gaussian GAMs. The canonical link is the identity function, giving the standard linear-Gaussian model.

The Gaussian family supports three link functions:

  • identity() – the canonical identity link g(mu) = mu.
  • log() – the log link g(mu) = log(mu), useful when the mean must be positive.
  • inverse() – the inverse link g(mu) = 1/mu.

  • Method Details

    • identity

      static Model identity()
      Identity link function (canonical link for Gaussian). g(mu) = mu, g^{-1}(eta) = eta.
      Returns:
      the identity link model.

    • log

      static Model log()
      Log link function for Gaussian. g(mu) = log(mu), g^{-1}(eta) = exp(eta). Useful when the mean must be positive.
      Returns:
      the log link model.

    • inverse

      static Model inverse()
      Inverse link function for Gaussian. g(mu) = 1/mu, g^{-1}(eta) = 1/eta.
      Returns:
      the inverse link model.
