Information

This function generates a random binary variable with the input of a continuous variable x from a quadratic logistic relation.

The probability of being 1 is calculated from the input x from a quadratic logistic relation with four predefined parameters A, B, C and D. Then a random generator generates the output, which should be a binary variable.

Interface

function logit1DQuadratic
  extends Modelica.Icons.Function;
  input Real x "Continous variable";
  input Real A = 1.0 "Parameter defining the quadratic logistic relation";
  input Real B = 1.0 "Parameter defining the quadratic logistic relation";
  input Real C = 1.0 "Parameter defining the quadratic logistic relation";
  input Real D = 1.0 "Parameter defining the quadratic logistic relation";
  input Integer stateIn[Modelica.Math.Random.Generators.Xorshift1024star.nState] "State of the random number generator";
  output Boolean y "Binary variable";
  output Integer stateOut[Modelica.Math.Random.Generators.Xorshift1024star.nState] "New state of the random number generator";
end logit1DQuadratic;

Revisions

• December 6, 2024, by Michael Wetter:
  Refactored implementation of random number calculations, transfering the local state of the random number generator from one call to the next.
  This is for #4069.
• July 20, 2018, by Zhe Wang:
  First implementation.
