摘要：In this paper we point out a seemingly overlooked problem in some well known fits of hadron abundances to the statistical hadronization model published in literature. This is concerned with the replacement of measured hadron yields with ratios of yields in the fit data sample. We show that this is a statistically incorrectmethod implying a significant bias in the assessments of freezeout parameters.
