Additional Example of Multivariate Embedding
In this example, you use the same data set as in Example of Multivariate Embedding, but reduce the data to three dimensions instead of two.
1. Select Help > Sample Data Folder and open Cytometry.jmp.
2. Select Analyze > Multivariate Methods > Multivariate Embedding.
3. Select CD3 through MCB and click Y, Columns.
4. Enter 3 next to Output Dimensions.
5. (Optional.) Click the gray disclosure icon next to Advanced Options, and enter 1234 for the Seed.
Note: Entering the seed above enable you to reproduce the results shown in this example.
6. Click OK.
Figure 11.4 Example of a 3D t-SNE Plot
Compared to the two-dimensional reduction, the three-dimensional reduction improves the clustering of the data. There are more distinct clusters visible in the 3D t-SNE plot as compared to the two-dimensional scatterplot in Figure 11.2.
Tip: You can rotate the grid to view the clusters more clearly.
