Abstract:

Is doing Path Analysis a good use of time? In my humble opinion the answer is a rather emphatic no, except for one exception (which I'll discuss below). Almost always Path Analysis tends to be a sub optimal use of our time, resources and any money that is expended on buying tools that do 'great' Path Analysis.
