Who found top-down processing?
In 1970, psychologist Richard Gregory stated that perception is a constructive process that depends on top-down processing. He explained that past experience and prior knowledge related to a stimulus help us make inferences. For Gregory, perception is all about making the best guess or a hypothesis about what we see.

Is parametric estimation top-down?
Differences between analogous and parametric estimating:
Analogous is considered top-down and is less accurate than parametric. Analogous estimating uses an “analogy” – comparing a past similar project to your current project. Parametric is more accurate, specifically when the underlying data is scalable.
