Enhancing precision in population variance vector estimation: a two-phase sampling approach with multi-auxiliary information

To enhance precision in estimating unknown population parameters, an auxiliary variable is often used. However, in scenarios where required information on an auxiliary variable is partially or fully unavailable, two-phase sampling is commonly employed. The challenge of estimating the variance vector...
