pyStoNED: A Python Package for Convex Regression and Frontier Estimation
pyStoNED:用于凸回归与前沿估计的 Python 软件包
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 the multivariate convex regression and related techniques such as convex quantile regression and convex expectile regression have bridged the long-standing gap between the conventional deterministic-nonparametric and stochastic-parametric methods.…
