Using a 'Google PageRank Calculator' is by far the best way to test the effects of links on the PR of the pages on a website (unless you're a clever mathematician). The results can be very surprising and often the opposite of what one would expect. For example, additional outgoing links on a page can actually produce an increase in PR for that page.

Added: there's one in particular that lets you create a grid for a site into which various link strategies can be entered and automatically tested to see the resulting PR effects on all pages. Of course this does not show real PR, but is very useful for comparing one approach against another.
