我用的是OxMetrics6的oxedit，这是我运用A Package for Estimating, Forecasting and Simulating Arfima Models: Arfima package 1.04 for Ox中第一段程序的运行结果，谁能解释下为什么出错了……arfima package是1.04的。
Ox Console version 6.21 (Windows/U) (C) J.A. Doornik, 1994-2011
This version may be used for academic research and teaching only
F:\统计软件\OxMetrics6\Ox\lib/normtest.ox : Link error: 'arfima' cannot load dll
F:\统计软件\OxMetrics6\Ox\lib/normtest.ox : Link error: 'fracsigma' undefined function

Ox reports errors: exit code= 1!!
