Module sampling 

Stratified sampling and Latin hypercube designs — seeded, exact stratification of the unit interval / hypercube.

Functions

latin_hypercube

An n x dims Latin hypercube: every dimension is exactly stratified (one point per stratum), with independent random pairings across dimensions. Deterministic per seed.

stratified_normals

n stratified standard normals (stratified uniforms through the inverse normal CDF).

stratified_uniforms

n stratified uniforms: exactly one jittered draw per stratum [i/n, (i+1)/n). Cuts the variance of smooth 1-D integrands from O(1/n) to O(1/n^3). Deterministic per seed.
