matsize too small-经管之家官网！

本人在做非平衡动态长面板样本，用了xtlsdvc模型，有12940行数据，变量有16个，命令为：
xtlsdvcah epu so turn size rmha peah qfii ehat rfah largest per top earning dividend t,initial(ab) first bias(3) vcov(100)
stata报错为：matsize too small。我觉得关键是提醒的下面两句但没看懂什么意思。
matsize must be at least 12089
(you have 12089 instruments)
r(908);
求教该如何改正
