请问take a draw of e from f(e)是啥意思啊?其中,f(e)是e的密度函数
以下是原文:
Rather than solve the integral analytically,it can be approximated
through simulation.Simulation is applicable in one form or another
to practically any specification of h and f .Simulation relies on the
fact that integration over a density is a form of averaging.Consider the
integral ¯t =积分符号t(ε) f (ε) dε,where t(ε) is a statistic based on ε which has
density f (ε).This integral is the expected value of t over all possible
values of ε.This average can be approximated in an intuitively straightforwardway.
Take numerous draws of ε from its distribution f ,calculate
t(ε) for each draw,and average the results.This simulated average is an
unbiased estimate of the true average.It approaches the true average as
more and more draws are used in the simulation.

就是平移多少个单位阿 ,take a draw of e from f(e)就是将密度函数的e平移或者移动,你最好把上下文给我
