Nonlinear regression fits a conditional mean whose dependence on its parameters is nonlinear. In a <normal distribution> observation model, the likelihood is based on residuals $y_i-m(x_i,\theta)$. Nonlinearity can create parameter trade-offs, asymmetric uncertainty and several posterior regions, so <prior predictive checks> and <Markov chain Monte Carlo convergence diagnostics> can be especially useful.
