Estimation Approach

Hi ,

We use a Client provided tool (Spread sheet) for effort estimation for our project .
We need to fill following details in that tool :-
1. If we think a new java class needs to be created for implementing the solution , we will fill the complexity of the class that will be created .
2. Our prior experience on implementing a similar java class .
etc..

And the tool will give us the effort based on our input.

I got to know from Wiki that there are several kinds of estimation approaches .
1. Analogy-based estimation
2. WBS-based (bottom up) estimation
3. Parametric models
4. Size-based estimation models[11]
5. Group estimation
6. Mechanical combination
7. Judgmental combination

Under which of these approached do our approach fall in ??

How do you arrive at this complexity? What is filled/expressed?


Our prior experience on implementing a similar java class.


In time or...??


etc..

means?
