Chapter 15 Performing Categorical Response Analysis 385<br />

The Categorical Platform<br />

The Categorical Platform<br />

The Categorical platform has capabilities similar to other platforms. The choice of platforms depends on<br />

your focus, the shape of your data, <strong>and</strong> the desired level of detail. Table 15.1 shows several of JMP’s analysis<br />

platforms, <strong>and</strong> their strengths.<br />

Table 15.1 Comparing JMP’s Categorical Analyses<br />

Platform<br />

Distribution<br />

Fit Y By X: Contingency<br />

Pareto Plot<br />

Variability Chart:<br />

Attribute<br />

Fit Model<br />

Partition, Neural Net<br />

Specialty<br />

Separate, ungrouped categorical responses.<br />

Two-way situations, including chi-square tests, correspondence<br />

analysis, agreement.<br />

Graphical analysis of multiple-response data, especially<br />

multiple-response defect data, with more rate tests than Fit Y By X.<br />

Attribute gauge studies, with more detail on rater agreement.<br />

Logistic categorical responses <strong>and</strong> generalized linear models.<br />

Specific categorical response models.<br />

The strength of the categorical platform is that it can h<strong>and</strong>le responses in a wide variety of formats without<br />

needing to reshape the data.<br />

Launching the Platform<br />

Open Failure3Freq.jmp in the Quality Control folder located in the sample data. Click on Analyze ><br />

<strong>Modeling</strong> > Categorical to obtain the launch dialog. The platform has a unique launch dialog. The<br />

buttons select groups of columns (as opposed to single columns like other JMP dialogs) for each of the<br />

situations.
