Then the rearranged confidence interval, defined by the rearranged upper and lower endpoint functions, is monotonic, shorter in length in common norms than the original interval, and covers the target ...

Research from all publishers In recent years, significant strides have been made by introducing new classes of fuzzy-interval-valued functions and developing corresponding integral inequalities.

The authors describe a new method for constructing confidence intervals. Their idea consists in specifying the cutoff points in terms of a function of the target parameter rather than as constants.
