Scripts

• InvaPactSim.R: script setting up simulation for 3 regions of set assessment characteristics, and the calculation of omega (weighted impact magnitude), mean omega per invasive species, and InvaPacts (affected species-weighted omega per invasive species)
• InvaPact conf sensitivity.R: script testing changes in the confidence of one region's assessments to determine affect on mean omega differences among regions
• InvaPact impact sensitivity.R: script testing changes in the impact magnitude of one region's assessments to determine affect on mean omega differences among regions
• InvaPact assessment sensitivity.R: script testing changes in the maximum number of assessments per invasive species in one region to determine affect on mean omega differences among regions
