Exam 18: Discriminant and Logit Analysis

When the dependent variable is binary, the logit model can also be used instead of two-group discriminant analysis.

The hit ratio is the number of variables found to be significant by the discriminant analysis.

Discriminant functions are linear combinations of the predictor or independent variables, which will best discriminate between the categories of the criterion or dependent variable (groups).

The nature of dependent and independent variables in the binary logit model is similar to that in ________.

In two-group discriminant analysis it is possible to derive only one discriminant function.

Discuss the similarities and differences among ANOVA, regression, and discriminant analysis (Table 18.1 in the text).

If there are 10 groups and 8 predictors, how many discriminant functions can be estimated?

Discriminant analysis can be conducted via all of the following except ________.

The null hypothesis in discriminant analysis, that in the population, the means of all discriminant functions in all groups are not equal, can be statistically tested.

In discriminant analysis, there is no multicollinearity in the predictor variables. Therefore, there is no ambiguous measure of the relative importance of the predictors in discriminating between groups.

Which of the following is not one of the steps involved in the "formulating the problem" step in discriminant analysis?

Also referred to as discriminant loadings, the structure correlations represent the simple correlations between the predictors and the discriminant function in discriminant analysis.

The logit model falls somewhere between regression and discriminant analysis in application.

As one of the statistics associated with discriminant analysis, ________ are obtained when the unstandardized coefficients are multiplied by the values of the variables and the products are summed and added to the constant term.

When the criterion variable has two categories, the technique is referred to as multiple discriminant analysis.

Discriminant analysis is available in EXCEL.

When conducting discriminant analysis, the analysis sample is that part of the total sample used to check the results of the estimation sample.

If you are using the leave-out option of SPSS, you are at the ________ step of discriminant analysis.

Cox and Snell R square and Nagelkerke R2 are measures of model fit used in ________.

The ________ is a test of significance of the logistic regression coefficient based on the asymptotic normality property of maximum likelihood estimates.
