Categorical data analysis with Practical Application

The main purpose of this study is to find out vectors that can be inserted to the statistical analysis of certain groups of variables which are formed as a result of a certain condition depending on categorical data (i.e. Qualitative variable ).Many statistical models have been discussed to deal with this condition in order to have a discriminate function or to have variables by which we can specify the condition gradually. Depending on the importance of the inserted variable in that condition, a theorem form of this sensitive variable has been derived . Some applications have been also used in this paper.
