For Google Panda, is it better to use relative or absolute internal links ?

Depends on your site really and how you want each page to be accessed. You may have to use absolute ones if you want certain pages to be accessed in https and others in http. Relatives won't work well.

Another issue is with content management. If you manage the site via an admin folder and want to preview some content within the folder, the relative paths may point to the wrong path, using absolute paths prevents these problems.

I am not 100% sure how googlebot views identical links exposed in different modes and depends on the configuration. To be on a safe side in these cases I will use absolute internal links. And keep an eye on the configuration vs what the bot indexes. There are various mistakes that can cause undesirable effects.

What you read there it's because of relative paths.
