In a Inventory of highway truck in that I am working, I need to find the mean value of the each iten of the imputs and the standard deviation as well.
But the data are "no distribution" and only the mean is here.
How can I find the standard deviation?
Uncertainty distribution
Re: Uncertainty distribution
Hi Masabara,
well this depends on the database, the uncertainty is not provided for all datasets and even within databases provided by one provider, not all "packages" might contain an uncertainty distribution. Ecoinvent unit process packages have an uncertainty distribution though, obtained via the pedigree approach in ecoinvent (which you can again discuss about).
Best wishes,
Andreas
