Positive Coaching Alliance (PCA) is an American non-profit organization which strives to create a positive youth sports environment. [ 1 ] Founded in 1998, [ 2 ] PCA has established 18 chapters nationwide and has delivered more than 20,000 live group workshops to over 19.2 million youths. [ 3 ]
Principal component analysis (PCA) is a linear dimensionality reduction technique with applications in exploratory data analysis, visualization and data preprocessing.. The data is linearly transformed onto a new coordinate system such that the directions (principal components) capturing the largest variation in the data can be easily identified.
The scree plot is used to determine the number of factors to retain in an exploratory factor analysis (FA) or principal components to keep in a principal component analysis (PCA). The procedure of finding statistically significant factors or components using a scree plot is also known as a scree test .
The 2014 guaranteed algorithm for the robust PCA problem (with the input matrix being = +) is an alternating minimization type algorithm. [12] The computational complexity is () where the input is the superposition of a low-rank (of rank ) and a sparse matrix of dimension and is the desired accuracy of the recovered solution, i.e., ‖ ^ ‖ where is the true low-rank component and ^ is the ...
In signal processing, independent component analysis (ICA) is a computational method for separating a multivariate signal into additive subcomponents. This is done by assuming that at most one subcomponent is Gaussian and that the subcomponents are statistically independent from each other. [1]

PCA is affiliated with A Beka Academy, a correspondence-school system that uses the A Beka Books curriculum. The A Beka Academy sells DVDs of PCA teachers recorded while teaching live classes at PCA. All student test scores and grades for those enrolled in A Beka Academy are sent to and recorded at the A Beka Academy offices.
