Detailed Description

Description of the class TLogTriangularDistribution.

This class defines a stochastic attribute following a LogTriangular distribution.

The definition of this distribution is that if a random variable $ x $ follows a LogTriangular distribution, the random variable $ \ln(x) $
follows a Triangular distribution.

User parameters are the bounds of the range $ [x_{min},x_{max}] $, and the mode $ x_{mode} $.

The constraint on these parameters is: $ 0 < x_{min} < x_{mode} < x_{max} $

Probability Density Function (PDF):
  • $ f(x) = 2 * \ln(x/x_{min}) / ( x * \ln(x_{max}/x_{min}) * \ln(x_{mode}/x_{min}) ) $ for $ x \in [x_{min},x_{mode}] $
  • $ f(x) = 2 * \ln(x_{max}/x) / ( x * \ln(x_{max}/x_{min}) * \ln(x_{max}/x_{mode}) ) $ for $ x \in [x_{mode},x_{max}] $
  • $ f(x) = 0 $ otherwise
Cumulative Distribution Function (CDF):
  • $ F(x) = 0 $ for $ x < x_{min} $
  • $ F(x) = (\ln(x/x_{min}))^2 / ( \ln(x_{max}/x_{min}) * \ln(x_{mode}/x_{min}) ) $ for $ x \in [x_{min},x_{mode}] $
  • $ F(x) = 1 - (\ln(x_{max}/x))^2 / ( \ln(x_{max}/x_{min}) * \ln(x_{max}/x_{mode}) ) $ for $ x \in [x_{mode},x_{max}] $
  • $ F(x) = 1 $ for $ x > x_{max} $
Inverse CDF:
  • $ F^{-1}(p) = \exp \left( \ln(x_{min}) + \sqrt{p * \ln(x_{max}/x_{min}) * \ln(x_{mode}/x_{min})} \right)$ for $ p \in [0,F(x_{mode})] $
  • $ F^{-1}(p) = \exp \left( \ln(x_{max}) - \sqrt{(1-p) * \ln(x_{max}/x_{min}) * \ln(x_{max}/x_{mode})} \right)$ for $ p \in [F(x_{mode}),1] $
