    projection pursuit directions. The statistical properties of the estimators based on such contrast functions are analyzed under the assumption of the linear mixture model‚ and it is shown how to choose contrast functions that are robust and/or of minimum variance. Finally‚ we introduce simple fixed-point algorithms for practical optimization of the contrast functions. These algorithms optimize the contrast functions very fast and reliably. 1 Introduction A central problem in neural network research

    In the given function‚ respond is a binary function‚ which is dependant on the other explanatory variable which aligns with the requirement of the linear probability model (LPM). This is an extention to the zero conditional mean condition which assumes that E(ul(resplast)‚(avggift)‚(propresp)‚(mailsyear))=0 and hence allow for E(ylx) to omit the error term producing P(respond = 1lx)= β(0)+ β(1) resplast+ β(2)avggift+ β(3)propresp+ β(4)mailyear.
