Assigning priors for parameters constrained to a simplex region
Paul M. Goggans, Lei Cao, R. Wesley Henderson · AIP conference proceedings · 2014
This paper examines the problem of assigning a prior pdf for N positive parameters z = {z1,z2,⋯,zN} that are dependent in such a way that their sum is bounded by a known constant. It also derives a set of functions that map N independent and uniformly distributed parameters to the parameters z with the known dependance.
