Exploring Data in Two Dimensions


Overview of Exploring Data in Two Dimensions

This chapter describes how to use SAS/IML Studio to examine relationships between pairs of variables.

You can explore the relationship between two (or more) nominal variables by using a mosaic chart. You can explore the relationship between two variables by using a scatter plot. Usually the variables in a scatter plot are interval variables.

If you have a time variable, you can observe the behavior of one or more variables over time with a line plot. You can also use line plots to visualize a response variable (and, optionally, fitted curves and confidence bands) versus values of an explanatory variable.

You can create and explore maps with a polygon plot.
