A reformulation of least-absolute-values and minimax model fitting problems as differentiable constrained minimization problems is considered and optimality conditions for their solutions are derived. Applying these conditions to generalized weighted sum models, measures are obtained for the resolution of highly similar terms in the models from the available observations.
