Actually, the loadings are quite different from the coefficients. The
loadings are simply correlations of the original values to the scores for a
PCA factor. The coefficients, on the other hand, allow one to compute the
scores. There is a coefficient for each variable. The coefficient is
multiplied with the standardized variable and then added to the next
coefficient multiplied by its standardized variable ets. The general
formula
