402 JMP Starter Appendix A
The Model Category
Fit Y by X Clicking the Fit Y by X button, or choosing Analyze > Fit Y by X, launches a report
platform for each pair of columns in the active data table that are assigned x and y roles for the
analysis.
The four sub-buttons under Fit Y by X lead directly to one of the four models within the Fit Y by X
platform:
Oneway If x has a nominal or ordinal analysis type and y is continuous, clicking the Oneway
button and making your selections in the window plot the distribution of y values for each
discrete value of x and computes a one-way analysis of variance table.
Bivariate If both x and y have continuous analysis types, clicking the Bivariate button and
making your selections in the window displays a scatterplot.
Contingency If both x and y have a nominal or ordinal modeling type, clicking the Contingency
button and making your selections in the window displays a contingency table and a mosaic bar
chart.
Logistic If x is continuous and y is nominal or ordinal, clicking the Logistic button and making
your selections in the window performs a logistic regression and displays a family of logistic
probability curves.
The chapters “Bivariate Scatterplot and Fitting,” “One-Way ANOVA,” “Contingency Tables Analysis,”
and “Simple Logistic Regression” of JMP Statistics and Graphics Guide cover these four cases.
The Model Category
The Model category (Figure A.4) gives choices for fitting all types of models—from simple regression
and analysis of variance to complex nonlinear fits.
