Simplex random variable
WebbA unit simplex is a vector with non-negative values whose entries sum to 1. For instance, \ ( [0.2,0.3,0.4,0.1]^ {\top}\) is a unit 4-simplex. Unit simplexes are most often used as parameters in categorical or multinomial distributions, and they are also the sampled variate in a Dirichlet distribution.

Webb1 jan. 1993 · Random basis (“open”) vectors are transformed into compositional vectors by dividing each vector's components by the sum of its components. The second algorithm uses a coordinate transformation to map uniform random vectors in a d -dimensional hypertetrahedron into uniformly distributed compositional variables on the d + 1 … Webb1 nov. 2024 · The Random Variables are generally represented using an uppercase letter. For e.g. for above experiment I would write it as H = {0,1,2}. This being said, the mapping of outcomes of sample space (Ω= {H,T}) to (real) numbers seems pretty deterministic i.e. there is no randomness here in the mapping (function) aspect.
