Question 5

An important consideration when assessing a classification procedure is the cost of classification.

Accepted Answer

A) True 
 B)False

Question 6

Discriminant functions are:

Accepted Answer

A)   Linear combinations of the original (predictor)  variables that maximize the between-to-within association, as measured by the sum-of-squares and cross-products (SSCP)  matrices.
B)   Uncorrelated linear combinations of the original (predictor)  variables that maximize the between-to-within association, as measured by the sum-of-squares and cross-products (SSCP)  matrices.
C)   Correlated linear combinations of the original (predictor)  variables that maximize the between-to-within association, as measured by the sum-of-squares and cross-products (SSCP)  matrices.
D)   Uncorrelated linear combinations of the original dependent variables that maximize the between-to-within association, as measured by the sum-of-squares and cross-products (SSCP)  matrices.E) None of the above
F) C) and D)

Question 7

The final step in the interpretation of discriminant analysis results is to:

Accepted Answer

B)   Determine the extent to which group differences support the functions generated by reviewing group means for each function as presented in the table of Functions at Group centroids.
C)   Determine the extent to which groups support the functions generated by reviewing group means for each function as presented in the table of Functions at Group centroids.
D)   Determine the extent to which groups support the functions generated by reviewing group variance for each function as presented in the table of Functions at Group centroids.E) B) and C)
