expand_attribute_levels

Expands the attributes and levels to the wide format. The nested list is
padded with zeros where alternative specific attributes are present to ensure
that we can work with square matrices.

Contemporary software commonly used to design stated preference experiments are expensive and the code is closed source. This is a free software package with an easy to use interface to make flexible stated preference experimental designs using state-of-the-art methods. For an overview of stated choice experimental design theory, see e.g., Rose, J. M. & Bliemer, M. C. J. (2014) in Hess S. & Daly. A. <doi:10.4337/9781781003152>.
