Combined uncertainty

We start with the determination of the input estimates x 1

, ..., x

N

Each input estimate x i

is obtained from a distribution of possible values of

the input quantity X .

i

This probability distribution may be:

a) frequency based , that is, based on a series of N observations X i , k of X i ; ∑ = N 1 ki i x x ,
