#PRINCIPAL COMPONENT ANALYSIS XLSTAT HOW TO#

It is a projection method as itВ projects observations from a p-dimensional space with p variables to a k-dimensional space (where k < p) so as to conserve the maximum amount of information (information is measured here through the total variance of the dataset) from the initial dimensions.

PrincipalВ Component AnalysisВ is one of the most frequently used multivariate data analysis methods.

We also provide many free learning resources on the web, such as a tutorial on how to run PCA in XLSTATВ as well as a guide to choose an appropriate data mining or multivariate data analysis method. Copy your PCA coordinates from the results reportВ to use them in further analyses. Feel free to customize your correlation circle, your observations plot or your biplots as standard Excel charts. Also, you can perform rotations such as VARIMAX. You can run your PCA on raw data or on dissimilarity matrices, add supplementary variables or observations, filter out variables or observations according to different criteria to optimize PCA map readability. XLSTAT proposes several standard and advanced options that will let you gain a deep insight into your data. XLSTAT provides a complete and flexible PCA feature to explore your data directly in Excel. It is widely used in biostatistics, marketing, sociology, and many other fields.

Principal Component Analysis ( PCA) is a powerful and popular multivariate analysis method that lets you investigate multidimensionalВ datasets with quantitative variables.
