Crossing variables lets you use simple correspondence analysis to analyze three-way and four-way contingency tables.
The following example shows row crossing. Column crossing is similar. Suppose you have two variables. The row variable, Gender, has two levels: male and female. The column variable, Age, has three levels; young, middle aged, elderly.
| Male | Young |
| Male | Middle aged |
| Male | Elderly |
| Female | Young |
| Female | Middle aged |
| Female | Elderly |
By default, Minitab orders text values alphabetically. The order previously shown will only show if you define a custom value order.
