discriminant analysis

 Discriminant analysis 

 



A technique for analyzing data when the dependent variable is categorical on nominal scale. 

The predictor or independent variables are interval in nature. 

For e.g.: 

The dependent variable may be the choice of a brand of laptop (A, B and C) and the independent variables may be ratings of attributes on a 7-point Likert\ scale. 


When the dependent variable has two categories, the technique is known as two group discriminant analysis. 


When three or more categories are involved, the technique is referred to as multiple discriminant analysis. 


In two – group case, it is possible to derive only one discriminant function but in multiple discriminant analysis, more than one function may be computed.

STAGES OF NEW PRODUCT DESIGN

 STEPS INVOLVED IN DEVELOPING NEW PRODUCT DESIGN: IDEA GENERATION: The design process begins with understanding the customer needs. Ideas for a new product can come from several sources.
