Chinese Buddhist canon
According to A.K. Warder, the Ekottara Āgama references 250 Prātimokṣa rules for monks, which agrees only with the Dharmaguptaka Vinaya, which is also located in the Chinese Buddhist canon. He also views some of the doctrine as contradicting tenets of the Mahāsāṃghika school, and states that they agree with Dharmaguptaka views currently known. He therefore concludes that the extant Ekottara Āgama is that of the Dharmaguptaka school.
