Mathematical analysis of ecoinvent data
- Matrix scatter plots of selected impact category results for all unit processes in ecoinvent, limited to amounts smaller than twice the mean; 1: acidification acc. to EDIP 2003, 2: eutrophication acc. to CML 2001, 3: eutrophication acc. to EDIP 2003, 4: human health acc. to Ecoindicator 99 (I,I) 5: human health acc. to Impact2002+ 6: human toxicity acc. to CML 2001 7: human toxicity acc. to EDIP 2003
Project goal
The project 'mathematical analysis of ecoinvent data' has three main objectives. First, aim is to look for structures in data, and to possibly detect inconsistencies and errors in data. Second, aim is to explore different methods and tools available from multivariate statistics and elsewhere, in regards to their potential for detecting structures and for quality assurance. And third, aim is, based on point 1 and 2, to develop and characterise one or several possible strategies for an automated quality assurance of ecoinvent data.
Project description
To analyse the ecoinvent data sets several methods and tools were tested with a view of their skills. For example plausability checks, statistical analysees and procedures, statistical tests, cluster analyses, or distribution tests were applied. These analyses were realised partly in Acess, partly in Excel or in R, an open source software.
Time period
2008 - 2009
