用EVIEWS做出错了：
NOTE: X-12-ARIMA will not compute the ACF of the squared residuals for
a set of residuals that is less than ten years long.
ERROR: Multiplicative or log additive seasonal adjustment cannot be
performed when preadjustment factors are derived from a regARIMA
model for data which have not been log transformed.
Check the values for the power or function arguments of the
transform spec and mode of the x11 spec.

这是什么意思啊？
