Unformatted text preview: 1 (taste) and y 2 (odor). 4. Test whether the 8 chemical characteristics can be regarded as statistically independent. 5. Perform a Principal Components Analysis using all 10 variables, and determine the actual dimensionality of the space in which the data fall (i.e., determine the number of principal components that would adequately describe these data). 6. Perform Factor Analyses using all 10 variables. After determining the number of factors needed, compare the results produced from using both the iterated Principal Factor Method and the Maximum Likelihood method. Use a Varimax Rotation with both methods. Specifically, which variables load on which factors, and do the 2 methods produce the same results? Recognizing your lack of expertise in the field of oenology, make an attempt at interpreting the factors....
