Unstacked Results Table
Figure 9.5 Stacked Results Table
Note the following about the stacked results table:
• The data table columns used in the analysis appear in the table.
• The results table includes every element in the platform report that you are bootstrapping. In this
example, the report is the Parameter Estimates report from a Bivariate model in Fit Y by X. The
elements are Term, Bias, Estimate, Std Error, t Ratio, Prob>|t|.
• The BootID• column identifies the iteration of the bootstrap process. The rows where BootID• = 0
correspond to the original estimates. Those rows are marked with an X and have the excluded row state.
If you selected the Split Selected Column option, an unstacked results table also appears. See “Unstacked
Results Table” on page 252.
Unstacked Results Table
When you right-click a report column and select Bootstrap, select Split Selected Column to create a data
table of unstacked results. The report item that you right-click on is the one that gets unstacked into a
separate table. For example, in Figure 9.6, the Estimate column from Figure 9.5 is split into two columns
(Displacement and Intercept), one for each level of Term.

The BootID• column identifies the iteration of the bootstrap process. The row where BootID• = 0
correspond to the original estimates. That row is marked with an X and has the excluded row state.
