To estimate the function \(f\), one could use the parametric and nonparametric methods or neoclassical and frontier models, of which methods are classified based on the specification of \(f\) and error term \(\varepsilon\) (see Kuosmanen and Johnson, 2010).
3 ημέρες πριν · <p>Shape-constrained nonparametric regression is a growing area in econometrics, statistics, operations research, machine learning, and related fields. In the field of productivity and efficiency analysis, recent developments in multivariate convex regression and related techniques such as convex quantile regression and convex expectile regression have bridged the long-standing gap between the ...
