Where is the statistical code location for adding Google Analytics to a blog built with Typecho?

I added Google Analytics in the header.php statistics code, GA has been informed that the statistical code is missing, although said to be lost, but also see a little statistics, but the amount of statistical data is not correct, I would like to ask you to add the statistical code on which page?
