Software Features

The SurveyEngine software is a browser-based platform allowing creation, simulation, data collection and analysis for academic-grade primary research. It has been purpose-designed for choice experiments and can also be used for standard questionnaires. The main features are described below. Examples of the versatility can be seen on the demonstrations page. Interested researchers are invited to sign up for a free trial.

Choice Experiment Specification

  • Simple user interface for specifying alternatives, attributes, and levels.
  • The input of text, images, and rich media.
  • Attribute linking allowing synchronization of levels.
  • Attribute space described independently of design and layout.
  • Multiple experiments possible within a single study.

Experiment Layout

  • Arbitrary positioning and styling of attributes.
  • Highly realistic experiments are possible.
  • Standard table layouts as default.
  • Real-time image layering and compositing.

  • Design levels coverage checking.
  • Recording of both treatment and actual scenario levels rendered.
  • Automatic random treatment allocation.
  • Optionally blocking or specific allocation schemes possible.

Modelling

  • Automated one-click ‘workhorse’ MNL main-effects modelling
