Quantitative Sensitive QuestionRandomized Response Technique (RRT)Cluster SamplingIn this paper, total probability formulas and classic sampling theories were applied to deduce formulas for the estimation of the
In pursuit of the ultimate atomic efficiency of noble metals, substantial efforts have been focused on the synthesis and application of catalysts with exclusively isolated single-atom sites (also known as single-atom catalysts, SACs)9,10,11,12. Although SACs could in principle achieve 100% dispers...
To deal with huge datasets, a sampling-based method called Clustering LARge Applications (CLARA) [112] might be utilized. CLARA's concept is that instead of considering the entire collection of items, a tiny subset of the original objects is chosen as the dataset's representations. PAM [111]...
Clustering performance using Nyström method is directly dependent on the selection of sampling points, i.e., more number of samples lead to better approximations. But increasing the sampling rate is also not favorable in case of big data problems. So, multiple extensions in Nyström techniques...
Each process performs sampling in different overlapping energy ranges, as indicated by different colors in the first three panels of the figure. The first panel shows the converged WL histograms per process converged up to a flatness condition of c = 0.995. Each histogram contains 22 bins ...

Appendix A: Sampling variability To assess the variability of clustering performance across different samples, we generated 50 datasets for each synthetic setting considered in Sect. 3.1, and computed clusterings via DBSCAN applied directly and to 2D UMAP-5 embeddings. Figure 8 shows box plots of ...
Since sampling points can contain several PSUs, the number of SSUs per sampling point and batch may vary. As the “Heidelberg” stratum consists only of one municipality, selection of individuals or households is carried out in a single-step simple random sampling process. The net sample size ...

An explanatory sequential method for qualitative data collection [20] was used, meaning that the quantitative data results informed qualitative research sampling and data collection. From the 70 facilities in the intervention arms, 28 health facilities (14 per arm) were purposively selected to reflect...
