Percent Change Variables Changed Sign

There is a potential problem, if you have a percent change result value of less than -100. This would mean that the corresponding levels value had changed sign. That might be contrary to the theory of your model, and could sometimes cause inaccurate solutions.

ViewSOL checks percent change variables as it reads in a solution and warns you (with a sound and a red notice) if there are such values. If so, the variables which contain elements less than -100% will be listed in the solution description. To discover which elements had strange values, you must inspect individual variable values yourself.
