Determinación del punto óptimo de potencia de paneles fotovoltaicos en base a variables difusas mediante el modelo de Liu Jordan
(2020-10)
This document focuses on solar generation, specifically on the optimum point of power delivered by the photovoltaic panel. To reach the end of the study, it is necessary to develop a mathematical model which must be followed ...
Testing for skewness and kurtosis in the one-way error components model
(Elsevier Inc, 2013-11)
This paper derives tests for skewness and kurtosis for the panel data one-way error component model. The test statistics are based on the between and within transformations of the pooled OLS residuals, and are derived in ...
Tests for normality in linear panel data models
(Stata Press, 2015-04)
A new Stata command, xtsktest, is proposed to explore non-normalities in linear panel data models. The tests explore skewnessand excess kurtosis allowing researchers to identify departures away from gaussianity in both ...

The perils of counterfactual analysis with integrated processes
(2017)
Recently, there has been a growing interest in developing econometric tools to conduct counterfactual analysis with aggregate data when a "treated" unit suffers an intervention, such as a policy change, and there is no ...
Optimal Parameter Estimation of Solar PV Panel Based on Hybrid Particle Swarm and Grey Wolf Optimization Algorithms
The performance of a solar photovoltaic (PV) panel is examined through determining its internal parameters based on single and double diode models. The environmental conditions such as temperature and the level of radiation ...

Effectiveness of corporate finance valuation methods: Piotroski score in an Ohlson model: the case of Mexico
(Universidad ESAN. ESAN EdicionesPE, 2014-12-30)
This study applied the Piotroski score for 63 selected companies of Mexico, for the period 2005 to 2011. The Piotroski score provides an evaluation on the historical financial performance of a company, with the evaluation ...
