We use Bayes' probability theorem to analyze many-pole fits of hadron
propagators. An alternative method of estimating values and uncertainties of
the fit parameters is offered, which has certain advantages over the
conventional methods. The probability distribution of the parameters of a fit
is calculated. The relative probability of various models is calculated.Comment: 4 pages, 6 figures, Latex with espcrc2.sty, uuencoded compressed tar
