Sampling populations, calculating weighted estimates, and accounting for errors, outliers, and uncertainty are important steps in our work to produce recreational catch statistics. There are two broad ...

NOAA Fisheries' Marine Recreational Information Program responds to questions about different types of survey errors, how they impact our estimates of recreational catch, and what we’re doing to ...

This paper proposes a novel logarithmic-type estimator for the estimation of the population mean under stratified random sampling when a single auxiliary variable is available. By employing a ...

Statistical estimation in survey sampling encompasses a range of methods designed to infer population parameters from observed data in a manner that is both unbiased and efficient. Traditional ...

Sampling is a technique in which samples are drawn at random (without any favor or bias). For this, suitable measures or procedures may be laid down and adopted according to the nature and ...
