Seasonality in annual data? Problem or not?

[Joe Zonda]

Hello, I have a panel data at an annual frequency. When I use the xtline command to get the linear plots, my data have obvious fluctuations and when I do further analyses, the results are not coming out as desired. I wonder if I should care about seasonality in annual data. Thank you!

Dear Joe Zonda
You will elicit response, if you had used Stata forum(your post presently is in Mata). To deal with seasonalities, why dont you have a trend dummy or say year dummy. Please look here
