Anyone know how to seasonally adjust data that have a lunar new year effect? (e.g. China or Taiwan industrial production data). I know the census x12 program has this option, but I do not see it available in the eviews command. Thanks.
X12 has too many options to be completely supported in EViews. Lunar New Year effect is not one of the supported options.
When you run X12, EViews 1) write your X12 executing commands (or specifications) and your data into files, 2) call x12 to execute the commands, and 3) import the X12 output sheet and data into EViews.
I suspect you can also write your own command file and then have EViews call x12 and execute the commands in the file. To do this you must write the x12 specification file and then execute x12 through EViews via EViews command 'X12' with the options SFILE which indicates the location of your specification. I've haven't done this myself so you'll have to experiment this one your own. Perhaps others might help you further. You might want to look at the command reference for information.
