invalid_dummy_coding: Find dummy-coded attributes that are not correctly specified
In spdesign: Designing Stated Preference Experiments
invalid_dummy_coding R Documentation
Find dummy-coded attributes that are not correctly specified
Description
Dummy-coded attributes must have the levels 1, 2, ..., K, where 1 is the
base level, and exactly K - 1 priors, one for each level except the base
level. Only the number of levels matters for the design, and using
1, 2, ..., K ensures that the expanded dummy-coded attributes and priors are
named and ordered consistently.
Usage
invalid_dummy_coding(x)
Arguments
x
An object of class utility
Value
A character vector with the names of dummy-coded attributes that are
not correctly specified. Empty if there are none.
