Extropy of order statistics applied to testing symmetry

On Dynamic Survival Past Extropy Properties‎

“…where f t (x) = f (x)/F (t), x > t. The J t (X) is suitable to measure information when uncertainty is related to the future. For more recent works on extropy, one can also refer to Alizadeh and Jarrahiferiz ( 2019), Noughabi and Jarrahiferiz (2020), Qiu and Jia (2018), Jose and Sathar (2019), Qiu (2017), and Krishnan et al (2020) and the references therein.…”
