Treatment of uncertainties from the TFractionFitter

Hello,

     I am using TFractionFitter to fit the data distribution with the templates from Monte Carlo simulation to extract their respective fractions. The Fitter gives us the fractions with the errors. The problem is how to disentangle the error into statistics and systematics parts. The error must have some part as statistical, but, clearly it has systematics too since it varies the shape of the templates while fitting. Can you please help me with this?

Thanks.
