On the Correlation between Random Variables and their Principal Components
Zenon Gniazdowski
The article attempts to find an algebraic formula describing the correlation coefficients between random variables and the principal components representing them. As a result of th…
On the Analysis of Correlation Between Nominal Data and Numerical Data
Zenon Gniazdowski
The article investigates the possibility of measuring the strength of a linear correlation relationship between nominal data and numerical data. Correlation coefficients for variab…
Principal Component Analysis versus Factor Analysis
Zenon Gniazdowski
The article discusses selected problems related to both principal component analysis (PCA) and factor analysis (FA). In particular, both types of analysis were compared. A vector i…
On the clustering of correlated random variables
Zenon Gniazdowski, Dawid Kaliszewski
In this work, the possibility of clustering correlated random variables was examined, both because of their mutual similarity and because of their similarity to the principal compo…
