This package provides functions for estimation population ratio (calibrated) under two phase sampling design, including the approximate variance of the ratio estimator. The improved ratio estimator can be applicable for both the case, when auxiliary data is available at unit level or aggregate level (eg., mean or total) for first phase sampled. Calibration weight of each unit of the second phase sample was calculated. Single and combined inclusion probabilities were also estimated for both phases under two phase random [simple random sampling without replacement (SRSWOR)] sampling. The improved ratio estimator's percentage coefficient of variation was also determined as a measure of accuracy. This package has been developed based on the theoretical development of Islam et al. (2021) and Ozgul (2020) . authors: - family-names: Islam given-names: Dr. Sadikul email: sadikul.islamiasri@gmail.com - family-names: Yeasin given-names: Dr. Md email: yeasin.iasri@gmail.com - family-names: Muruganandam given-names: Dr. M. email: mail2mmm20@gmail.com - family-names: Madhu given-names: Dr. M. email: madhupmd@gmail.com repository: https://sadikulislamiasri-hub.r-universe.dev commit: 17e6463f46e011dd33ba5a4f9f709adbe2600b94 date-released: '2022-07-01' contact: - family-names: Islam given-names: Dr. Sadikul email: sadikul.islamiasri@gmail.com
