Probability Distribution Functions with INA: Info & Tutorial

The Probability Density module includes four analysis tools, all related to the Probability Distribution Functions (PDFs).

The INA module devoted to PDFs includes four sub-modules, identified by corresponding buttons of the right hand side control panel:

  1. PDFs computes the probability distribution functions for a range of scales;
  2. Flatness computes the parameter with the same name related to the fourth order moment of the PDFs;
  3. OPR computes a parameter to be used in an attempt to rescale all the computed PDFs;
  4. OPR Rescaling applies the One Parameter Rescaling (OPR) procedure based on the parameter computed by OPR

An example is shown in the screen capture included below.
