predict e, resid

动态面板不能运行啊，用上述命令总是出现

option resid not allowed
r(198);

predict newvar, [option]

xb xb, fitted values; the default
stdp calculate standard error of the fitted values
ue u_i + e_it, the combined residual
xbu xb + u_i, prediction including effect
u u_i, the fixed- or random-error component
e e_it, the overall error component */

谢谢！可是xtreg 可以运行ue，可是动态面板不能

请问楼主知道怎么解决这个问题了吗
