What Criteria Could You Differentiate Among Multiple...

Questions 1. How would you differentiate among multiple discriminant analysis, regression analysis, logistic regression analysis, and analysis of variance? The main difference is in the number of independent and dependent variables and the way in which these variables are measured. Note the following definitions: In Multiple discriminant analysis (MDA), the predictor or independent variables are metric and the single criterion or dependent variable is non metric . In Regression Analysis , both the multiple independent variables and the single dependent variable are metric. In Analysis of Variance (ANOVA) , the single independent variable is non metric and the multiple dependent variables are metric. 2.

How would you determine the optimum cutting score? For equal group sizes, the optimum cutting score is defined by ZA + ZB ZCE = ---------- N ZCE is the critical cutting score value for equal size groups, ZA is the centroid for group A and ZB is the centroid for Group B and N is the total sample size. For unequal group sizes, the optimum cutting score is defined by NAZA + NBZB ZCU = ------------ NA + NB ZCU = is the critical cutting score value for unequal size groups, NA is the sample size for group A and NB is the sample size for Group B 5. How would you determine whether the classification accuracy of the discriminant function is sufficiently high relative to chance classification? There has to be some chance criterion that should be established. This is generally a fairly straight-forward function of the classifications that is used in the model and of the sample size. The authors then suggest the criterion that the classification accuracy or the hit ratio must be at least twenty five percent greater than by chance. Other test can be to use a test of proportions to examine for the significance between the obtained hit-ratio proportion and the chance criterion proportion . 6.

Segmentation as a process consists of segment identification, segment selection and the creation of marketing mixes for target segments. The outcome of the segmentation process should yield true market segments which meet three criteria: (a) Group identity: true segments must be groupings that are homogeneous within segments and heterogeneous acrossRead MoreBrand Loyalty12984 Words   |  52 Pagesproposed model, demonstrating that brand loyalty can be considered as truly loyal only when mediated by a high degree of affective and cognitive brand conviction, and attitude strength. Advertising and marketing implications for the relationships among the six constructs under different manipulation conditions are discussed.

Conceptually, they define brand attachment, articulate its defining properties, and differentiate it from brand attitude strength. From a measurement perspective, they develop and validate a parsimonious measure of brand attachment, test the assumptions that underlie it, and demonstrate that it indicates the concept of attachment. They also demonstrate the convergent and discriminant validity of this measure in relation to brand attitude strength. Managerially, they demonstrate thatRead MorePsychology Testing Worksheet9642 Words   |  39 PagesValidity and Reliability The overall problem with psychological tests concerns their ability to measure what they are supposed to measure. The accuracy, or usefulness, of a test is known as its validity. For example, suppose you wanted to develop a test to determine which of several job applicants would work well in a bank. Would an arithmetic test be a valid test of job success? Well, not if the job required other skills, such as manual dexterity or social skills. Construct ValidityRead MoreInfluencing Factors for the Selection of Mobile Phone Service Providers9769 Words   |  40 Pagesselecting an operator’s services.

Therefore, research to enrich current knowledge about what affects individuals to use mobile banking is required. Consequently, this study employs the Unified Theory of Acceptance and Use of Technology (UTAUT) to investigate what impacts people to adopt mobile banking. Through sampling 441 respondents, this study empirically concluded that individual intention to adopt mobile banking was significantlyRead MoreBrand Building Blocks96400 Words   |  386 Pagesmotivation to build brands. The second reason, the proliferation of competitors, reduces the positioning options available and makes implementation less effective. The third and fourth reasons, the fragmentation in media and markets and the involvement of multiple brands and products, describe the context of building brands today, a context that involves a growing level of complexity. The remaining reasons reflect internal pressures that inhibit brand building.
