JMP is a data discovery tool used in both (1) the exploratory phase and (2) the analysis phase, of experimental and theoretical work. The density ellipse shows the extent of data, the center of mass, the least-squares fit line, and the degree of correlati on between a selected dependent variable and a selected independent variable. When superimposed, the ellipses of similar variables for different classes show and contrast their sameness and differences. The example used is pharmaceutical data in the area of cancer research.
