Comparison of dimension reduction methods for DEA under big data via Monte Carlo simulation

Chen, Zikang; Han, Song - In: Journal of management science and engineering 6 (2021) 4, pp. 363-376

Data with large dimensions will bring various problems to the application of data envelopment analysis (DEA). In this study, we focus on a "big data" problem related to the considerably large dimensions of the input-output data. The four most widely used approaches to guide dimension reduction...

Bias Reduction and Goodness-of-Fit Tests in Conditional Logistic Regression Models

Sinha, Samiran (contributor); Wang, Suojin (contributor) - 2010

This dissertation consists of three projects in matched case-control studies. In the firstproject, we employ a general bias preventive approach developed by Firth (1993) to handlethe bias of an estimator of the log-odds ratio parameter in conditional logistic regression bysolving a modified...
