The V–Dem Measurement Model: Latent Variable Analysis for Cross-National and Cross-Temporal Expert-Coded Data

Minimizing the Weights dispersion in Cross-Efficiency Measurement in data envelopment analysis

  Because of the piecewise linear nature of the data envelopment analysis (DEA) frontier, the optimal multipliers of the DEA models may not be unique. Choosing weights from alternative optimal solutions of dual multiplier models is one of the most frequently studied subjects in the context of DEA. In this paper, the authors have been inspired by the idea of Cooper et al. (2011) to propose a li...

Latent variable measurement models and path analysis

What is a latent variable? • A variable that is not observable or is not directly measurable. • A variable that is measured with error or can only be measured with error. • A latent variable can be used to represent a 'true' variable which is measured with error, OR a single conceptual variable, OR a construct which is a summarization of a complex concept. Examples of 'true' variables that are ...

Introducing a secondary goal for evaluating DMUs by cross efficiency in data envelopment analysis

One way to rank DMUs in DEA is the cross efficiency method. In this method, the efficiencyof each DMU is calculated by other DMUs optimum weights, which makes the ranking moreacceptable for managers. Existing alternative optimum weights in cross efficiency methodlead to several ranks for DMUs. Several secondary goals have introduced to avoid thisproblem, till now. In this paper, a new model is ...
