An MDS routine
 a. operates through a set of formulas, as in regression, that yield the best fit
  b. always attempts to maximize the stress level of the distance data
  c. is iterative, determining a good initial guess and continuing to derive better estimates
  d. none of the above

Question 2

Explain how regression differs from correlation.

Answer to Question 1

C
Unlike regression, an MDS routine is iterative, determining a good initial guess and continuing to derive better estimates to lower stress and better represent the data.

Answer to Question 2

Regression analysis is a technique for measuring the linear association between a dependent and an independent variable. Although simple regression and correlation are mathematically equivalent in most respects, regression is a dependence technique where correlation is an interdependence technique. A dependence technique draws a distinction between dependent and independent variables. An interdependence technique does not make this distinction and simply is concerned with how variables relate to one another.
