This article describes how to do a Latent Class Analysis in Displayr. Latent Class is a statistical technique for grouping together similar observations (i.e., creating segments).

## Requirements

A data set containing the variables that you want to use as inputs to the cluster analysis segmentation.

## Method

1. Login into Displayr and load a document.

2. Load the data set that contains the variables that you want to use as inputs to the Latent Class Analysis.

3. From the toolbar menu, select **Anything > Advanced Analysis > Cluster ****> Latent Class Analysis**.

4. On the next screen, select the variables that you want to include as inputs to the Latent Class Analysis from the **Available data** list. The selected variables will be displayed on the **Data to display** list. As an example, I've used a data set containing statements on a 5-point agree/disagree scale about attitudes around mobile technology.

5. Select the number of segments you want to create:

- Select
**Work out number of groups automatically**if you want Displayr to determine the number of groups with the greatest differences, or - Select
**Specify the number of groups**and enter a value for the number of segments you want to create.

For this example, I've selected the latter option and entered a value of 4.

6. OPTIONAL: Apply a filter if you want to create a segmentation for a specific subgroup.

7. OPTIONAL: Select a weight if you want the input variables weighted.

8. Click the **Create Latent Class Analysis** button.

The Latent Class output will then be generated. The first column shows the distribution of responses for the entered sample used in the analysis. Each additional column shows the response distributions for each of the segments.

A new single response variable is added to the bottom of the data set called "Latent Class Analysis" with a date/time stamp in the variable label. This variable contains the segment assigned to each respondent. Create a table using this variable to see the distribution of segment assignments.

9. To get a diagnostic report of your latent class analysis, **Anything > Advanced Analysis > Cluster > Diagnostic > Analysis Report**

The results are as follows:
