Qualitative inputs

Hi everyone,

I was wondering if there were any tools in UQLab in dealing with qualitative (rather than quantitative) inputs for a engineering system.

Let’s say we have a system with inputs x1 and x2. x1 is a quantitative input with certain distribution, while x2 is a qualitative input such as the type of simulation algorithm, whether to include some modeling features or not, or ordinal variables.

In this case, it that possible to do sensitivity analysis in order to determine whether x1 or x2 has more impact on the output of the system?

Thanks a lot in advance!
