UniformSimplex

RiskAMP Random Distribution Functions

This function samples a random probability vector of length n, where each component is non-negative and the total sums to 1. The distribution is uniform over the n-1 simplex, meaning each point in that space has equal probability density.

Example

Each time you recalculate the spreadsheet the individual component values will change but will always sum to 1.

This function can be used to divide a value into random components. For a discrete version, see UniformIntegerSimplex.
