Definitions for "Path analysis"
a procedure associated with multiple regression involving a diagram indicating the strength and direction of influences between several variables, enabling calculation of direct and indirect causal pathways.
(IEEE) Analysis of a computer program [source code] to identify all possible paths through the program, to detect incomplete paths, or to discover portions of the program that are not on any path.
Blizzard Tracker allows users to view the path a visitor takes from their web site's home page to and from any other page in the site. This provides an excellent means for evaluating the usability, relevance and appeal of various paths through a web site. If usage of a certain link is lower than expected, the link text or the placement on the page may need to be changed. If visitors tend to leave the site after landing on a certain page, perhaps the content or design of that page needs work.

this is often a computer generated (although it can be done by hand) profile taking all the information gathered in the site survey and combining it with the specifications of the radio that is expected to be used. It takes into account the basic line of sight, curvature of the earth (this starts to be important in approximately 6 miles), the frequency and the freznel zone required for the radio, as well as rain fade for the area being considered.
