MBA 740 Module 7

Multivariate data analysis

A statistical approach analyzing multiple variables simultaneously.

Variate

A mathematical representation of a set of variables with one equation.

Dependence techniques

Multivariate procedures predicting observed dependent variables using independent variables.

Multiple regression analysis

A dependence technique predicting a dependent variable based on multiple independent variables.

Discriminant analysis

A technique that determines group membership based on predictor variables.

Multivariate analysis of variance (MANOVA)

A statistical method that assesses the differences between group means on multiple dependent variables.

Multivariate analysis of covariance (MANCOVA)

An extension of MANOVA that includes covariates.

Wilks’ Lambda (Λ)

A multivariate test statistic to assess group mean vector differences.

Cutting score

A benchmark in discriminant analysis for classifying group membership.

Confusion matrix

A table comparing predicted to actual group membership for model accuracy.

Logistic regression

A statistical method for predicting categorical outcomes based on independent variables.

Likelihood value

An indication of the predictive capability of logistic regression.

Entropy or pseudo R-squared

An assessment of predictive power in logistic regression analogous to R-squared.

Odds ratio (e^β)

A measure of the impact of an independent variable on the likelihood of an outcome.

Statistical significance

A measure used to determine if an effect is likely due to chance in regression analysis.
