New ways to combine data from multiple environmental area frame surveys of a finite population are being introduced. Environmental surveys often sample finite populations through area frames. However, to combine multiple surveys without risking bias, design components (inclusion probabilities, etc.) are needed at unit level of the finite population...

... order to have equal first-order expected number of inclusions for all units, the sample frames were expanded around the area of interest in each direction by the size of the inclusion zone radius, guaranteeing that all inclusion zones are fully within the sample frames. In Table 1, the designs are described in further detail. ...Similar publications
The present study proposes a generalized mean estimator for a sensitive variable using a non-sensitive auxiliary variable in the presence of measurement errors based on the Randomized Response Technique (RRT). Expressions for the bias and mean squared error for the proposed estimator are correctly derived up to the first order of approximation. Fur...
