Normal score backward

This task takes data that follows a standard normal distribution, also known as a gaussian distribution, and transforms it to follow a different distribution. If you transformed your data to a gaussian distribution to do some calculations, this task lets you transform it back to its original distribution.

Parameters

• source (geoscience object reference)
  • A geoscience object reference that points to a one-dimensional continuous attribute inside a pointset or downhole-intervals object.
• target (geoscience object reference)
  • A geoscience object reference that tells the task where to save the result. It must point to an attribute inside a pointset, downhole-intervals, regular-3d-grid, or regular-masked-3d-grid object.
• distribution (geoscience object reference)
  • A geoscience object reference that points to a non-parametric-continuous-cumulative-distribution object. The target attribute will follow this distribution.

Example

For more information, see the normal score backward API reference.

Tips

• The source and target can use the same object, but they don't have to.
