Abstract: We select ~20,000 metal-rich star-forming galaxies from the SDSS DR2 to study the R23P method suggested by Pilyugin et al. for metallicity estimates. The oxygen abundance derived from their revised R23P method is ~0.19 dex lower than those derived from the previous one, and ~0.60 dex lower than the Bayesian abundances obtained by the MPA/JHU group. These abundance discrepancies strongly correlate with the P parameter and weakly depend on the log(R23) parameter.
