Time Control Chart – Log Logistic Distribution

B., SriRam; A., Suhasini; R.R.L., Kantam (2019-05-01)

The time to failure of a product is considered as a quality characteristic of following Log-Logistic distribution (β = 3). Control limits are evaluated for the time to failure. Life time data are compared with the control ...
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 ...
