What are formal statistical tests for heavy-tailedness?

Aug 27, 2015 ... I want to confirm how to implement Parametric VaR using a Student t-distribution. The formula is one that I have found but I'm not sure if its correct. Student's t-Distribution ... s^2=1/(N-1)sum_(i=1 ... degrees of freedom is implemented in the Wolfram Language as StudentTDistribution[n]. ... -distribution ... Like the normal distribution, the t- distribution is symmetric. If you think about folding it in half at the mean, each side will be the same. Like a standard ... TDist: The Student t Distribution.

Student t-distributions are very close to the standard normal distribution, and become closer as the number of degrees of freedom increases. The Student's t-distribution has more probability in its tails than the standard normal distribution. The Student-t distribution is symmetrically peaked, and its peak is located at μ , the location paramter. The peak's width is dictated by scale parameter σ , ...
