Different methods of circuit analysis

[pairofstrings]

Hybrid equivalent model
Graphical determination
Is there more to this list?

I am studying the book on Electronic circuit analysis by Godse.

Is the following part of circuit analysis methods?

Nodal Analysis
Mesh current analysis
Superposition
Impulse response
Convolution

How to differentiate between the two lists?

When should we use Hybrid equivalent model technique to analyze any circuit?

I need answers. Can anyone please tell me the significance of Hybrid equivalent model of a transistors and it's applications?
I came across H parameter representation of a transistor while I was studying 'Small signal Low frequency transistor amplifier circuits' in Common Emitter, common collector, common base configuration.

Thanks!
