"WebThe normalized entropy is a measure of relative uncertainty . The value of normalized entropy lies between 0 and 1, so NH a (θ) ∈ [0, 1]. This leads to standardized measures which can be compared with one another . An analog measure 1− NH a (θ), called the information index, serves to measure the reduction in uncertainty .
