I used your pca.xls file in order to calculate the scores for each component. I used your equation:
PC1 = 0.207 WDIM + 0.873 CIRCUM + 0.261 FBEYE + 0.326 EYEHDÂ + 0.066 EARHD + 0.128 JAW
PC2 = -0.142 WDIM -0.219 CIRCUM - 0.231 FBEYE + 0.891 EYEHB + 0.222 EARHD - 0.187 JAW
But I did not get the same scores as yours.
Could you tell me in this exercise what I must to input in WDIM, FBEYE, EARHD and JAW. I know that those names are for the variables, but does it means the standardized values for each variable?
