Advanced_delay

The advanced_delay plug-in delays the experiment for a pre-specified average duration plus a random margin.

  • Duration is the average duration of the delay in milliseconds.
  • Jitter is the size of the variation in the delay in milliseconds.
  • Jitter mode is how the jitter is defined:
    • Standard deviation will draw values from a Gaussian distribution with Jitter as the standard deviation.
    • Uniform will draw values from a Uniform distribution centered at Duration, with Jitter as the width.
