Unit 13: Multivariate Analysis




              MDS as a set of multivariate statistical  methods for  estimating the parameters in  and  Notes
               assessing the fit of various spatial distance models for proximity data.

              The output of MDS looks very similar to that of factor analysis and the determination of
               the optimal number of dimensions is handled in much the same way.

          13.8 Keywords

          Cluster Analysis: Cluster Analysis is a technique used for classifying objects into groups.

          Conjoint Analysis: Conjoint analysis is concerned with the measurement of the joint effect of
          two or more attributes that are important from the customers’ point of view.
          Discriminant Analysis: In this analysis, two or more groups are compared. In the final analysis,
          we need to find out whether the groups differ one from another.
          Factor Analysis: Factor Analysis is the analysis whose main purpose is to group large set of
          variable factors into fewer factors.

          Multivariate Analysis: In multi  variate analysis, the number  of variables to  be tackled are
          many.

          13.9 Review Questions

          1.   Which  technique would you use to measure the joint effect of various attributes while
               designing an automobile loan and why?
          2.   Do you think that the conjoint analysis will be useful in any manner for an airline? If yes
               how, if no, give an example where you think the technique is of immense help.
          3.   In your opinion, what are the main advantages of cluster analysis?
          4.   Which analysis would you use in a situation when the objective is to summarise information
               from a large set of variables into fewer factors? What will be the steps you would follow?
          5.   Which analysis would answer if it is possible to estimate the size of different groups?
          6.   Which analysis would you use to compare a good, bad and a mediocre doctor and why?
          7.   Analyse the weakness of principle component factor analysis.

          8.   Which multivariate analysis would you apply to identify specific customer segment for a
               company’s brand and why?
          9.   Critically  evaluate multidimensional scaling.

          10.  In your opinion what will be the disadvantages of having too many independent variables
               in an MR study?
