GeometricMean

(Weighted) geometric mean

Information

This information is part of the Business Simulation Library (BSL). Please support this work and ► donate.

The scalar output y is obtained as the geometric mean of the components of the input vector u. Optionally weights can be given, either as constants (weights) or as variable inputs (u_weights).

y = (sum_i x_i^w_i)^(1/sum_i w_i)

Notes


  • If useWeights = false then all weights are assumed to be one.

  • If any of the components of u is less than or equal to zero, the output y will be zero.

  • Negative weights will be set to zero.
