Data Envelopment Analysis
Data envelopment analysis (DEA) is a nonparametric method in operations research and economics for the estimation of production frontiers.Charnes et al (1978) DEA has been applied in a large range of fields including international banking, economic sustainability, police department operations, and logistical applicationsCharnes et al (1995) Emrouznejad et al (2016)Thanassoulis (1995) Additionally, DEA has been used to assess the performance of natural language processing models, and it has found other applications within machine learning.Zhou et al (2022)Guerrero et al (2022) Description DEA is used to empirically measure productive efficiency of decision-making units (DMUs). Although DEA has a strong link to production theory in economics, the method is also used for benchmarking in operations management, whereby a set of measures is selected to benchmark the performance of manufacturing and service operations. In benchmarking, the efficient DMUs, as defined by DEA, may not n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Non-parametric Statistics
Nonparametric statistics is the branch of statistics that is not based solely on parametrized families of probability distributions (common examples of parameters are the mean and variance). Nonparametric statistics is based on either being distribution-free or having a specified distribution but with the distribution's parameters unspecified. Nonparametric statistics includes both descriptive statistics and statistical inference. Nonparametric tests are often used when the assumptions of parametric tests are violated. Definitions The term "nonparametric statistics" has been imprecisely defined in the following two ways, among others: Applications and purpose Non-parametric methods are widely used for studying populations that take on a ranked order (such as movie reviews receiving one to four stars). The use of non-parametric methods may be necessary when data have a ranking but no clear numerical interpretation, such as when assessing preferences. In terms of levels of mea ...

Stochastic Frontier Analysis
Stochastic frontier analysis (SFA) is a method of economic modeling. It has its starting point in the stochastic production frontier models simultaneously introduced by Aigner, Lovell and Schmidt (1977) and Meeusen and Van den Broeck (1977). The ''production frontier model'' without random component can be written as: y_i = f(x_i ;\beta ) \cdot TE_i the best where ''yi'' is the observed scalar output of the producer ''i'', ''i=1,..I, xi'' is a vector of ''N'' inputs used by the producer ''i'', ''f(xi, β)'' is the production frontier, and \beta is a vector of technology parameters to be estimated. ''TEi'' denotes the technical efficiency defined as the ratio of observed output to maximum feasible output. ''TEi = 1'' shows that the ''i-th'' firm obtains the maximum feasible output, while ''TEi < 1'' provides a measure of the shortfall of the observed output from maximum feasible output. A stochastic component that describes random shocks affecting the production process is ad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
