Exam 18: Discriminant and Logit Analysis

What does it mean if the discriminant function is estimated and the square of the canonical correlation is .64?

In discriminant analysis,the criterion or dependent variable is ________ and the predictor or independent variables are ________ in nature.

Which of the following statements is not an objective of discriminant analysis?

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

In multiple discriminant analysis,the interpretation of results is aided by an examination of all of the following except ________.

Discriminant/logit analysis is similar to regression and ANOVA in which of the areas stated below (Table 18.1 in the text)?

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

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

The first step in discriminant analysis is to formulate the problem by identifying the objectives,the criterion variable,and the independent variables.

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

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

The Mahalanobis procedure is based on minimalizing a generalized measure of the distance between the two closest groups.

With the leave-one-out cross-validation option in SPSS,the discriminant model is re-estimated as many times as there are respondents in the sample.

The direct method is an approach to discriminant analysis that involves estimating the discriminant function so that all the predictors are included simultaneously.

The last step in conducting discriminant analysis is to interpret the results (Figure 18.2 in the text).

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.

Sometimes also called confusion or prediction matrix,the ________ contains the number of correctly classified and misclassified cases.

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.

As one of the statistics associated with discriminant analysis,the ________ (unstandardized)are the multipliers of variables when the variables are in the original units of measurement.
