The generalized mean, also known as the power mean or Hölder mean, is an abstraction of the quadratic, arithmetic, geometric, and harmonic means. It is defined for a set of n positive numbers xi by. [ 1] By choosing different values for the parameter m, the following types of means are obtained: maximum of. quadratic mean.
