各位大神，求教！
用stata做HLM，同时将3个自变量及13个高层变量设置为随机效应，结果一个命令运行了十几个小时结果还没报完，请问大家该如何提高运行速度呢？以下是我的命令，麻烦大神们帮我看看，拜托了，不胜感激！
其中party0 cadrevli0 recp0 是自变量；num_cmp  ind_park farmland_p fin_institu ance_temple sd_clan hi_prestige vill_tyrant church        qz_temple         budi_temple        tao_temple        oth_temple dummy_relifacility是高层次变量，模型中将二者都设置为随机效应，但是速度很慢很慢，求教如何提速，谢谢大家！
