Kitagawa–Oaxaca–Blinder decomposition

The Kitagawa–Oaxaca–Blinder (KOB) decomposition, or simply Kitagawa decomposition or Blinder–Oaxaca decomposition (), is a statistical method that explains the difference in the means of a dependent variable between two groups by decomposing the gap into within-group and between-group differences in the effect of the explanatory variable. The method was originally invented by sociologist and demographer Evelyn M. Kitagawa in 1955.
