Correlation matrix in base r
WebCollinearity as a function of the whole matrix. Even a high correlation between two variables, if it is below 1, doesn't necessarily make the whole correlation matrix singular; it depends on the rest correlations as well. For example this correlation matrix: 1.000 .990 .200 .990 1.000 .100 .200 .100 1.000 WebMar 25, 2024 · A correlation matrix is a matrix that represents the pair correlation of all the variables.
