  3. Confidenceforglass box models • Glass box modelscomputevaluesfor output quantities in dependency of input quantities. For everypurpose, defined in terms of output quantities, fulfilling the purpose means that the uncertaintydistribution on the output quantitiesshouldbesufficiently small. So we shouldknowthisuncertaintytoknowif the model result is OK. http://cdn.morguefile.com/imageData/public/files/h/hotblack/preview/fldr_2008_11_02/file0001766655282.jpg
