The latter since include maximum likelihood estimate of the GPD(generalized Pareto distribution ) model parameters to still include moment estimate etc.
后者既包括基于广义帕雷托分布（GPD）参数的极大似然估计，又包括矩法估计等。

In GPD model, a too low threshold will get biased estimates because the limit theorem does not apply.
在广义帕累托分布模型中，门限值过小，极限定理不成立，得到的估计是有偏的；

We present an implementation of the GPD method in a GMM-based system.
