Workspace Node: Tree Clustering (Joining) - Specifications - Quick Tab
The Tree Clustering (Joining) workspace node can be accessed from the Feature Finder, the ribbon bar, or the Node Browser. The Specifications - Quick tab is displayed by default when you open the specifications dialog box.
Element Name | Description |
---|---|
Variables | Click this button to display a variable selection dialog box. Note that Statistica interprets the selected variables as dimensions if Cases (rows) is selected in the Cluster drop-down list on the Specifications - Advanced tab; if Variables (Columns) is selected in the Cluster list, the selected variables will be interpreted as objects. |
Input file | The Input file drop-down list contains two options: Raw data and Distance matrix. |
Raw data | If you select Raw data, Statistica expects a standard raw data file as input. |
Distance matrix | If you select Distance matrix, the input matrix may either be a correlation matrix or a distance (dissimilarity) matrix with numbers indicating the distances or dissimilarities between objects. Statistica automatically determines the contents of the matrix (i.e., whether it contains correlations or dissimilarities, see Matrix File Format). If the input matrix is a correlation matrix (which indicates the similarity and closeness between objects), it is converted to distances before the analysis begins; specifically, all correlations are transformed as 1-Pearson r. |
MD deletion | Missing data can be deleted Casewise or by Mean Substitution depending on the selection in this group box. Note that the MD deletion options are only available if Raw Data has been specified as the Input file. |
Casewise | If this option button is selected, only cases that do not contain any missing data for any of the variables selected for the analysis will be included in the analysis. |
Mean substitution | If this option button is selected, missing data will be replaced by the means for the respective variables (for this analysis only, not in the data file).
Options / C / W. See Common Options. |
OK | Click the OK button to accept all the specifications made in the dialog box and to close it. The analysis results will be placed in the Reporting Documents node after running (updating) the project. |
