swop5 | R Documentation |
Facet-defining inequalities of the strict weak order mixture model for all 10 paired comparisons of 5 choice elements a,b,c,d,e in a 3-alternative forced-choice task (Regenwetter & Davis-Stober, 2012).
swop5
A list with 3 elements:
A
: Matrix with inequality constraints that define a polytope via A*x <= b
.
b
: vector with upper bounds for the inequalities.
start
: A point in the polytope.
options
: A vector with the number of options (=3) per item type.
