Launch the Latent Class Analysis platform by selecting Analyze > Clustering > Latent Class Analysis.
Latent Class Analysis Launch Window
The Latent Class Analysis platform launch window contains the following options:
Y
One or more categorical response columns that you want to analyze.
Weight
A column whose numeric values assign a weight to each row in the analysis.
Freq
A column whose numeric values assign a frequency to each row in the analysis.
ID
A column used to identify separate respondents. This identification is used in some output tables.
By
A column that creates a report consisting of separate analyses for each level of the variable. If more than one By variable is assigned, a separate analysis is produced for each possible combination of the levels of the By variables.
Number of Clusters
The number of clusters to be computed in the analysis.
Up to
Specifies a maximum number of clusters. If this number exceeds the value specified for Number of Clusters, a model report is produced with a number of clusters equal to each integer value in the range between Number of Clusters and Up to. These reports appear as part of a Fit Group outline.
After you click OK on the launch window, the Latent Class Analysis report appears.
