PageRank is a measure of the quality and quantity of incoming links to a specific web page. Period.
Any page on the web can pass PageRank to any other page according to the following formula:
PR passed =.85 * {PR of originating page} / {total # outgoing links on that page including internal navigation links}
So if the PR of your web page decreases, it is (primarily) because the PR of some of your incoming links have decreased, or the pages containing those incoming links have added new links (decreasing the value passed to your page).
Similarly, the PR of your page may increase as you add more incoming links, or as the PR of the originating pages increase.
It is a little bit more complicated than that in reality but that's basically it in a nutshell.

No, that has nothing to do with the question posed in this thread. Rather, that article discusses "limits" to the number of outgoing links on a page (and indirectly overall page size) from the viewpoint of getting spiders to crawl your pages.
Oh right,
It does explain some things about link juice... I thought this may be a little helpful.
Very interesting formula @minstrel. Is there any Matt Cutts(or any other Google worker) post or video regarding how the PR is calculated? No offense please.

I believe it's from the original Google patent but it has also been described in words in several posts from Googlers and others over the years.
You can find a lot more information than I can understand here: PageRank - Wikipedia, the free encyclopedia

Very interesting post i was also wondering how it was calculated, just curious. So ty a lot gentlemen 
Thanks for great resources. Now i can be confident in this too. Thanks for research and share.
Google uses dozens of factors to determine the rankings, such as Title text, body text, inbound link text and PageRank. PageRank isn't even the most important factor. It is often the case that pages beat higher PageRank pages because they are better optimized across the various factors for the particular search term.

Yes and no. It was created by the men who started Google, one of whom is Larry Page, and it was named PageRank after Larry Page. But it is indeed a measure of the quantity and quality of links pointing at any given specific page on the net.
