  • Constructor Details

    • StudentTDistribution

      public StudentTDistribution(int degreesOfFreedom)

  • Method Details

    • density

      public Real density(Real x)
      Description copied from interface: ProbabilityDistribution
      Probability density function (PDF) or probability mass function (PMF). f(x) = dP/dx for continuous, P(X = x) for discrete.
      Parameters:
      x - the value to evaluate density at
      Returns:
      the probability density or mass

    • mean

      public Real mean()
      Description copied from interface: ProbabilityDistribution
      Returns the mean (expected value) of this distribution.
      Returns:
      the mean

    • variance

      public Real variance()
      Description copied from interface: ProbabilityDistribution
      Returns the variance of this distribution.
      Returns:
      the variance

    • toString

      public String toString()
      Overrides:
