The stochastic frontier analysis is an econometric approach to efficiency measurement. The basic idea is the introduction of two error components, a random error term and an inefficiency term. For both terms, a distributional assumption is made, which facilitates maximum likelihood estimation.

Distance, revenue, cost and profit functions can always be written in the form of regression models with unobserved error terms representing statistical noise and different types of inefficiency. In practice, the noise components are almost always assumed to be random variables (i.e., stochastic).

Combining the Virtues of Stochastic Frontier and Data Envelopment Analysis
Operations Research, 2019A recent spate of research has attempted to develop estimators for stochastic frontier models that embrace semi- and nonparametric insights to enjoy the advantages inherent in the more traditional operations research method of data envelopment analysis.

A stochastic frontier approach to survival analysis
Journal of Applied Statistics, 2013In spite of the best set of covariates and statistical tools for the survival analysis, there are instances when experts do not rule out the existence of many non-observable factors that could influence the survival probability of an individual. The fact that every human body, sick or otherwise, strives to maximize time to death, renders the stochastic

Stochastic Frontier Analysis and Efficiency Estimation
2008Theoretically, a production function gives the maximum possible output with a given set of inputs. This is different from its common regression counterpart, which specifies the conditional mean of output. The production function defines a boundary or “frontier”, deviations from which can be interpreted as inefficiency.

Panel Data Stochastic Frontier Analysis
2015Stochastic frontier analysis based on cross-sectional data is hampered by the fact that only one observation is available for the estimation of two error components. Panel data containing several observations for each firm considerably improve the situation for estimating firm specific efficiency scores if some assumptions on the time path of ...

Stochastic Frontier Analysis for New Venture’s Innovation Performance
2011Innovation performance is an important indicator that examines if the new venture has the foreseeable future of development during the growing process. With SFA and the sample–historical data of 24 new establishment of 6-8 years start-ups, innovation performance of which were measured and analyzed and the variation of innovation performance and its ...
