Unique Solution.

[Cynderella]

Is the following statement true that :

"To get unique solution of each parameter in a model, number of equations must be greater than or equal to the number of parameters."

???

I would say as a rule of thumb it is true, but as an exact mathematical statement it is not. A good place to start is by considering the solutions to systems of linear equations.
