Witryna14 sie 2024 · Loadings are interpreted as the coefficients of the linear combination of the initial variables from which the principal components are constructed. From a numerical point of view, the loadings are equal to the coordinates of the variables divided by the square root of the eigenvalue associated with the component. The loadings are the … Witrynarotation. the matrix of variable loadings (i.e., a matrix whose columns contain the eigenvectors). The function princomp returns this in the element loadings. x. if retx is true the value of the rotated data (the centred (and scaled if requested) data multiplied by the rotation matrix) is returned.
