cycle: Cycling of attribute levels

In spdesign: Designing Stated Preference Experiments

Cycling of attribute levels

Description

Cycles the attribute levels to create a new design candidate. "Cycling replaces all attribute levels in each choice situation at the time by replacing the first level with the second level, second level with the third etc. Since this change affects all columns, cycling can only be performed if all attributes have exactly the same sets of feasible levels, (e.g., where all variables are dummy coded)." (p. 253).

Usage

cycle(x)

Arguments

x	A vector of attribute levels

Details

This part of the RSC algorithm is rarely invoked.

Value

A cycled design candidate
