Algunas observaciones acerca del uso de software en la estimación del modelo Half-Normal

Ortega Irizo, Francisco Javier; Gavilán Ruiz, José Manuel - In: Revista de métodos cuantitativos para la economía y … 11 (2011), pp. 3-16

Using the maximum likelihood method, in order to estimate Half-Normal stochastic frontier production models, entails several practical di±culties that, perhaps, have not been su±ciently emphasised. In employing FRONTIER software, we analyse the case in which the estimation obtained suggests...

Measuring exchange rate fluctuations risk using the value-at-risk

Akhtekhane, Saeed Shaker; Mohammadi, Parastoo - In: Journal of applied finance & banking 2 (2012) 3, pp. 65-79

case we deal with a single risk factor, so we will not use the Monte Carlo simulation method to measure the VaR and we will … only use the parametric and historical simulation methods for this purpose. The parametric method using the normal … distribution and historical simulation with exponentially weighted data and without weighting is used to calculate VaR. Finally …

Spurious rejections by Dickey-Fuller tests in the presence of an endogenously determined break under the null

Badillo Amador, Rosa; Belaire Franch, Jorge; Reverte … - In: Revista de métodos cuantitativos para la economía y … 9 (2010), pp. 3-16

Leybourne et al. (1998) have proved the possibility of a `converse Perron phenomenon' when conventional Dickey-Fuller tests are applied to deter-mine the order of integration of a time series. That is, if the true generating process is I(1) but with a break, frequent spurious rejections of the...
