Abstract
|
Ranked set sampling is considered as an alternative to simple random sampling and maximum ranked
set sampling is a very useful modification of ranked set sampling. In this paper we focused on information content
of ranked set sampling and maximum ranked set sampling with unequal samples in terms of past extropy measure
and also considered the information content of negative cumulative extropy and its dynamic version based on
maximum ranked set sampling and simple random sampling designs. We also compare ranked set sampling data,
maximum ranked set sampling data with simple random sampling and with each other. Also here we obtained
a new discrimination information measure among simple random sampling data, ranked set sampling data and
maximum ranked set sampling data for past extropy measure.
