(2006-09)
En este artículo se analiza la literatura reciente sobre los determinantes del altruismo en el marco de una red social. Se proponen dos variables explicativas para racionalizar resultados experimentales relativos al ...
Testing for seasonal unit roots in heterogeneous panels
This paper uses the approach of Im, Pesaran and Shin [Im, K.S., Pesaran, M.H., Shin, Y., 2003. Testing for unit roots in heterogeneous panels. Journal of Economics 115, 53-74.] to propose seasonal unit root tests for dynamic ...
Predicting the outcome of initial non-surgical endodontic procedures by periapical status and quality of root canal filling: a cohort study
To assess the previous periapical status and the quality of root canal filling as predictors of the outcome in initial non-surgical endodontic procedures. A retrospective cohort study was designed in which the presence of ...
Enhanced molecular visualization of root colonization and growth promotion by Bacillus subtilis EA-CB0575 in different growth systems
(Elsevier GmbH, 2018-01-01)
Bacillus subtilis EA-CB0575 is a plant growth-promoting bacterium (PGPB) associated with banana and tomato crops. Root colonization is an important trait for PGPB microorganisms and potentiates the bacterial effect related ...
Response surface models for OLS and GLS detrending-based unit-root tests in nonlinear estar models
In this article, we calculate response surface models for a large range of quantiles of the Kapetanios, Shin, and Snell (2003, Journal of Econometrics 112: 359–379) and Kapetanios and Shin (2008, Economics Letters 100: ...

Testing for seasonal unit roots in heterogeneous panels in the presence of cross section dependence
This paper presents two alternative methods for modifying the HEGY-IPS test in the presence of cross-sectional dependency. In general, the bootstrap method (BHEGY-IPS) has greater power than the method suggested by Pesaran ...
Unit-root tests based on forward and reverse Dickey-Fuller regressions
In this article, we present the command adfmaxur, which computes the Leybourne (1995, Oxford Bulletin of Economics and Statistics 57: 559-571) unit-root statistic for different numbers of observations and the number of ...
