Description

A helper function for polygram. Creates a list of constraints out of a formula, ms, ps and s.

Usage

formulas_to_constraint_list(form, ms, s, ps)

Arguments

form	a formula
ms	segrees of Bernstein densities
s	split points
ps	connectivity constraints

Details

Currently supported options are:

1. "convex", "concave"; both together produces straight line.

2. "decreasing", "increasing"; both together produces uniform.

3. "symmetric"

4. mean: Takes two "arguments", one in c("=", ">=", "=<") and a numeric in support.

5. moment: Takes three "arguments", one in c("=", ">=", "=<"), a numeric in support, and a natural specifying the moment.

6. quantile: Takes three "arguments", one in c("=", ">=", "=<"), a numeric

7. quantile: Takes three "arguments", one in c("=", ">=", "=<"), a numeric in support, and a float in (0,1) specifying the quantile.

Value

A list containing a 1.) a constraint matrix, 2.) lower bounds and 3.) upper bounds.
