Deletion of Symbolic analysis

Comment: At first glance, this looked like a real topic, but it's more like one person's thesis. Need reliable sources to show its importance. Also 'symbolic analysis' sounds like using it is using |neologism to attach a made-up meaning to a familiar-sounding phrase. No evidence that other writers use 'symbolic analysis' in this sense
