We propose two statistical methods to derive oxygen abundances in HII regions
and star forming galaxies and calibrate them with a sample of several hundred
giant HII regions in spiral and blue compact galaxies as well as of galaxies
from the Sloan Digital Sky Survey. We show the advantages of our new abundance
indicators over previous ones.
