Abstract: In a recent paper [Pan et al., Phys. Rev. B 84, 161307 (2011)], experimental data on spin splitting in the integer quantum Hall effect have been reported in a high mobility dilute two-dimensional (2D) electron gas with electron density as low as 0.2 $\ifmmode\times\else\texttimes\fi{}$ 10${}^{11}$ cm ${}^{\ensuremath{-}2}$. In this work, we show that an excellent quantitative description of these data can be obtained within the model of the magnetic-field-induced Stoner transition in the quantum Hall regime. This provides a powerful tool to probe the nontrivial density dependence of electron-electron interactions in the dilute regime of the 2D electron gas.
