  A selection of unfolding methods commonly used in High Energy Physics is
compared. The methods discussed here are: bin-by-bin correction factors, matrix
inversion, template fit, Tikhonov regularisation and two examples of iterative
methods. Two procedures to choose the strength of the regularisation are
tested, namely the L-curve scan and a scan of global correlation coefficients.
The advantages and disadvantages of the unfolding methods and choices of the
regularisation strength are discussed using a toy example.
