描述性统计量,如中位数、Q_1,Q_3和四分位间距,不受极端值的影响,称为抗干扰度量(resistant measures)。 五值概括法 变量的五值概括法(five-number summary)中包括的统计量为:最小观测值、第一四分位数、中位数、第三四分位数和最大观测值。 X_{最小}\quad Q_1\quad 中位数 \quad Q_3 \quad X...
This thought-provoking study demonstrates that MRSA infection rates began to decline prior to implementation of widespread infection control measures. These data suggest strain-specific factors have a substantial role in the epidemiology of MRSA. Article PubMed PubMed Central Google Scholar Clarridge, ...
Applying factor analysis to assess covariance between measures of zone-biased exploration further suggested that a common factor underlaid recall and renewal (Figures S1E and S1F). Combining this conditioned cue-place preference task with electrophysiological recordings allowed us to determine whether ...
The input data for the analysis consisted of matrices containing the band intensities of the analyzed samples. In addition, diversity measures were computed through the following methods: Richness (S) was determined by counting the number of bands present in each lane. Additionally, the diversity ...
We evaluated the assembly process of microbial communities, which is known to be strongly linked to the maintenance of plant health [25], based on the β-nearest taxon index (βNTI), which measures the mean phylogenetic distance between taxa of a community. We detected marked differences in β...
bedsore prevention measures, frequent nutritional support and blood tests require significant effort on the part of the medical staff. Considering these challenging circumstances, the ICU management of patients with SAH is associated with a prolonged hospital stay, high costs, and adverse effects that ...
Nevertheless, addi- tional research is needed to understand the mechanism behind this reduction better and identify potential preven- tive measures for patients experiencing this complication during tigecycline therapy. Furthermore, further investi- gation is required to evaluate the efficacy of ...
