I tried to apply first a PCA on the 4 variables (forcing the ordinal into numerical which is sometimes suggested), i get this graph: then i tried to do a FAMD (factor analysis of mixed data) which was recommended with the factominer package.Unfortunately there is not a lot of documentation about it. This is the output:

We will use the FactoMineR package to compute the PCA. FactoMineR is a really great package for exploratory data analysis, and it provides a great deal of output that we can use to visualize the results of the PCA. Before we begin, let’s go over the distinction between two important terms for the PCA implementation in FactoMineR. Jun 09, 2016 See full list on factominer.free.fr Recall that PCA (Principal Component Analysis) is a multivariate data analysis method that allows us to summarize and visualize the information contained in a large data sets of quantitative variables. See full list on rdrr.io Principal Component Analysis (PCA) Performs Principal Component Analysis (PCA) with supplementary individuals, supplementary quantitative variables and supplementary categorical variables. Missing values are replaced by the column mean. Principal component analysis (PCA) is a statistical procedure that uses an orthogonal transformation to convert a set of observations of possibly correlated variables into a set of values of linearly uncorrelated variables called principal components (Wikipedia).

Confirmatory Factor Analysis (CFA) is a subset of the much wider Structural Equation Modeling (SEM) methodology. We would like to show you a description here but the site won’t allow us. library(FactoMineR) FactoMine.pca <- PCA(vsd.transposed, graph = F) plot((FactoMine.pca), axes=c(1,2)) This plot looks fairly similar to the first one, but the proportion of variances explained by Dim 1 and 2 are quite different compared to the plot produced by plotPCA. library(FactoMineR) pca<-PCA(dta.cor, scale.unit=T) plot.PCA(pca,cex=1) and the result plot.

F. Husson, S. Le and J. Pages Principal component analysis (PCA) allows us to summarize and to visualize the information in a data set containing individuals/observations described by multiple inter-correlated quantitative variables. Each variable could be considered as a different dimension.

x: an object of class PCA. axes: a length 2 vector specifying the components to plot. choix: the graph to plot ("ind" for the individuals, "var" for the variables, "varcor" for a graph with the correlation circle when scale.unit=FALSE)

and hierarchical cluster analysis. Package ‘FactoMineR’ (PCA) when variables are quantita-tive, correspondence analysis (CA) and multiple correspondence analysis (MCA) when vari-ables are categorical, Multiple Factor Analysis when variables are struc-tured in groups, etc. and hierarchical cluster analysis. F. … Principal Component Analysis (PCA) Performs Principal Component Analysis (PCA) with supplementary individuals, supplementary quantitative variables and supplementary categorical variables. Missing values are replaced by the column mean. PCA with FactoMineR As you saw in the video, FactoMineR is a very useful package, rich in functionality, that implements a number of dimensionality reduction methods. Its function for doing PCA is PCA () - easy to remember!

As it seems I can only display ether the variables or the individuals with the built in ploting device: plot.PCA(pca1, choix="ind/var"). Principal component analysis (PCA) reduces the dimensionality of multivariate data, to two or three that can be visualized graphically with minimal loss of information. fviz_pca () provides ggplot2-based elegant visualization of PCA outputs from: i) prcomp and princomp [in built-in R stats], ii) PCA [in FactoMineR], iii) dudi.pca [in ade4] and epPCA [ExPosition]. The factoextra R package can handle the results of PCA, CA, MCA, MFA, FAMD and HMFA from several packages, for extracting and visualizing the most important information contained in your data.

Missing values are replaced by the column mean. Principal component analysis (PCA) is a statistical procedure that uses an orthogonal transformation to convert a set of observations of possibly correlated variables into a set of values of linearly uncorrelated variables called principal components (Wikipedia). FactoShiny is described with PCA and clustering but it can also be used for any principal component methods (PCA, CA, MCA or MFA). Tools to interpret the results obtained by principal component methods tential in terms of applications: principal component analysis (PCA) when variables are quantita-tive, correspondence analysis (CA) and multiple correspondence analysis (MCA) when vari-ables are categorical, Multiple Factor Analysis when variables are struc-tured in groups, etc.
