boninense . The presented findings suggest that the PCA model provides a general approach for handling, analysis and interpretation of large LC-MS datasets to reveal time-dependent changes of intracellular metabolites that may indicate G. boninense developmental process in vitro ....
但是由于学科语言不同,加上当时通讯不便,就在各个领域有了PCA的别名,比如最著名的有信号处理领域中的Karhunen–Loève transform,还有Hotelling transform 、proper orthogonal decomposition (POD), eigenvalue decomposition (EVD), factor analysis等等。更多的别名可参考https://en.wikipedia.org/wiki/Principal_component...
Genome sequencing of thousands of individuals usually generate tens of millions of SNPs, making it challenging for PCA analysis and interpretation. Here we present VCF2PCACluster, a simple, fast and memory-efficient tool for Kinship estimation, PCA and clustering analysis, and visualization based on...

Principal Component Analysis is a tool that has two main purposes: To find variability in a data set. To reduce the dimensions of the data set. PCA examples
Also, the interpretation of principal components can explain associations among variables that are not visible at first glance. It helps analyze the scattering of the observations and recognize the variables responsible for distribution. Now, we will use graphical representation to understand PCA. ...
In turn the Principal Component Analysis (PCA) is considered to possibly add value to existing approaches, and it allows for an interpretation of polarimetric synthetic aperture radar measurements using variables obtained via linear transformation. Starting with the Sinclair backscatter matrix S which ...
1. 准确的PCA和概率解释(Exact PCA and probabilistic interpretation) PCA 用于对具有一组连续正交分量(Orthogonal component译注: 或译为正交成分,下出现 成分 和 分量 是同意词)的多变量数据集进行方差最大化的分解。 在 scikit-learn 中,PCA被实现为一个变换器对象, 通过fit方法可以拟合出n个成分, 并且可以将...

PCA Interpretation in R Interpreting the results of PCA involves a detailed analysis of loadings and their relationships to the original variables. Loadings represent the correlations between the original variables and the principal components, providing insights into how much each variable contributes to...
