question about X11 X12 X13

[fi_charles]

I'm rather new to Eviews and have a basic question. I have a quarter series "Y" and would like to do the seasonal adjustment and store it as series "Y_adj". So in the program window I have a line:

Y.X12(M) Y_adj

After I run it, "Y_adj" series was NOT created. The same thing happens when I replace X12 with X13. But if I replace it by X11, it successfully creates the series "Y_adj". Can anyone help? Thank you.

The syntax for X12 is not the same as that for X11 or X13. Each has different syntax.

Notably, since X12 and X13 produce multiple output series, you cannot provide a single name for the resultant series. Rather, in the case of X12, you provide a name pattern.

See the object reference for more details.
