We consider Newton–Kantorovich regularization method for the implementation of Lavrentiev regularization method. Using general Hölder type source condition we obtain an error estimate. We also use the adaptive parameter choice strategy proposed by Pereverzev and Schock (SIAM J Numer Anal 43(5):2060–2076, 2005) for choosing the regularization parameter. © 2019, Springer-Verlag Italia S.r.l., part of Springer Nature.Adaptive parameter choice strategyBanach spaceLavrentiev regularizationm- accretive mappingsNewton–Kantorovich regularization methodNonlinear ill-posed problem
