New Median Ranked Set Sampling for Skew Distributions

Dinesh S., Bhoj; Debashis, Kushary (2019-05-01)

A new median ranked set sampling procedure for positively skew distributions (NMRSSS) is proposed and used to estimate population mean. The estimators based on the proposed scheme are compared with the estimators based on ...
On the Cartwright Power-of-Cosine Circular Distribution CPC,  - Some Distributional Properties and Characterizations

M., Shakil; M., Ahsanullah; B.M. Golam, Kibria (2019-05-01)

For modelling the directional spectra of ocean waves, Cartwright introduced a power-of-cosine circular distribution, (cf. Cartwright, D. E. (1963), “The use of directional spectra in studying the output of a wave recorder ...
Using Rank of the Auxiliary Variable in Estimating Variance of the Stratified Sample Mean

Shabbir, Javid; Gupta, Sat (2019-11-01)

We propose a generalized class of estimators for finite population variance using the auxiliary variable as well as rank of the auxiliary variable in stratified sampling. We identify many estimators as special cases of ...
