Hello, I'm wondering if there would be any complications with combining the results of separate IMPLAN models. We have 5 categories that will be included in the analysis. Is summing the outputs of the models as accurate as modeling the total expenditures all at once. I tested the independence of multifamily construction and single family construction as well as oil and gas and fisheries. No non-linearity of economic impacts was shown in either test. The sums of the two separate model outputs was the same as both industries modeled at the same time. Are there any exceptions to the linearity of impact(barring an industry going below zero)? Can I freely add together the results of separate models? Thank you, Peter
