I have one dependent categorical variable and other many explanatory categorical variables. The number of nominal values for any of these categorical variables may fall in range of 5-100. My objective is to explore the relationship between dependent categorical variable and any one of explanatory variable and to find out if there is any significant relationship.
The tools I can think of are like contingency tables with tests like chi-square etc. Are there any other specific suggestions?
Datasets that I am going to use are large with at least 50,000 datapoints (rows) and I am using spotfire (S+) for my analysis.
