 size="3">These toy examples illustrate how to implement general inequality constraints. They generate points uniformly over a restricted region of the square with corners at (1, 1) and (-1, -1). A dummy bernoulli variable is introduced and its corresponding proportion set to the step function of the required constraint. The only useful example is the parallelagram where x + y is constrained to be less than or equal to one, this idea can be used to model proportions for binary data instead of say logistic r
