Hi Rose,
What you intend to do is a bit unclear here... Firstly a "single-branch tree" is just a normal parameter tree. It doesn't mean you cannot have more than one parameter in the list. The "import parameter table" function is a convenience when you have many parameters to create. Instead of adding them one by one in the jEPlus GUI, you can edit them in a text file, which is generally quicker. After importing the text file, the parameter tree will be created for you.
Back to your question, if for example x1=0, x2=Suburbs, and x3=0.2 is a case you want to consider, you just need to create the parameters as usual. The combinatorial parameter shall be used when you only want to consider x1=0 and x2=City, but not x1=0 and x2=Suburbs and so forth. It allows you to specify the exact combinations, instead of letting jEPlus to explore all possible combinations.
