Dear Statalist,

I have some problem with a database cleaning. I have a panel database
of 15 years. I have to exclude the observations with an annual price
increases of more than 200 percent or a price declines of more than 60
percent.
Anyone could give me a suggestion?

Thank you very much

Daniele
