In the present paper, we focus on nonparametric methods and present a detailed numerical comparison of four different approaches to estimate the ED nonparametrically. The methods are briefly reviewed and their finite sample properties are studied by means of a detailed simulation study. Moreover, a data example is presented to illustrate the different concepts.enBinary response modelEffective dose levelIsotonic regressionLocal linear regressionNonparametric regressionOrder restricted inference004report
