  • Updated
Follow

Introduction

This feature can be used to obtain diagnostic information, referred to as the Grow Settings and Analysis Report, for a segmentation/tree output from Latent Class Analysis, Mixed-Mode Cluster Analysis or Mixed-Mode Tree.

 

Requirements

A Q project containing a Mixed-Mode Tree, Mixed-Mode Cluster Analysis and/or a Latent Class Analysis output. 

 

Method

To run the diagnostic analysis report: 

  1. Select any or multiple outputs from a Mixed-Mode Tree, Mixed-Mode Cluster Analysis and/or a Latent Class Analysis.
  2. Select Run Automate > Browse Online Library > Machine Learning > Diagnostic > Analysis Report to obtain the grow settings and analysis report for each selected segmentation output.

Example

Below are the results of running a Latent Class Analysis using several variable sets from a survey examining respondents' preferences for different types of cola.

After selecting the output and runnning Anything > Advanced Analysis > Cluster > Diagnostic > Analysis Report, the following report is obtained.

Technical details

If you modify any of the input data to your tree or update/rerun your analysis, you will need to rerun this feature to obtain the new analysis report. The output containing the report will show an error informing you of this.

Customizing the QScript

This QScript is written in JavaScript and can be customized by copying and modifying the JavaScript.

Customizing QScripts in Q4.11 and more recent versions

  • Start typing the name of the QScript into the Search features and data box at the top right of the Q window.

  • Create a new text file, giving it a file extension of .QScript. See here for more information about how to do this.
  • Modify the JavaScript (see QScripts for more detail on this).
  • Run the file using Automate > Run QScript (Macro) from File.
