**Plotting PCA (Principal Component Analysis)**

Implementing Principal Component Analysis (PCA) in R. Give me six hours to chop down a tree and I will spend the first four sharpening the axe. —- Abraham Lincoln... To make sense of an overabundance of information, you can use cluster analysis—which allows you to develop inferences about a handful of groups instead of an entire population of individuals—as well as principal components analysis, which exposes latent variables.

Principal Components Analysis: A How-To Manual for R Emily Mankin Introduction Principal Components Analysis (PCA) is one of several statistical tools available for reducing the dimensionality of a data set. Its relative simplicity—both computational and in terms of understanding what’s happening—make it a particularly popular tool. In this tutorial we will look at how PCA works, the how to make a can crusher out of metal 23/01/2017 · Principal Component Analysis in R Principal component analysis (PCA) is routinely employed on a wide range of problems. From the detection of outliers to predictive modeling, PCA has the ability of projecting the observations described by variables into few orthogonal components defined at where the data ‘stretch’ the most, rendering a simplified overview..

### Categorical principal components analysis is also known by the acronym CATPCA, for categorical principal components analysis. The goal of principal components analysis is to reduce an original set of variables into a smaller set of uncorrelated components that represent most of the information found in the original variables.

- No matter which package you decide to use for computing principal component methods, the factoextra R package can help to extract easily, in a human readable data format, the analysis results from the different packages mentioned above. factoextra provides also convenient solutions to create ggplot2-based beautiful graphs.

- Principal component analysis is equivalent to major axis regression; it is the application of major axis regression to multivariate data. As such, principal components analysis is subject to the same restrictions as regression, in particular multivariate normality, which can be evaluated with the MVN package. The distributions of each variable should be checked for normality and transforms
- Correspondence Analysis (CA), which is an extension of the principal com- ponent analysis for analyzing a large contingency table formed by two qualitative variables (orcategoricaldata).
