The derivation of the expected value is incorrect for probability analysis;
however, the sampling of the distribution is correct for uncertainty analysis.
The confusion is related to the MEF issue: open-psa/mef#27

The fix contains an error in the interval weights missing the interval length.

Nope, no error (false alarm)

contains wrong formula for the probability density.
