Revista Colombiana de Estadística, 2010 In this paper, we present an extension of the Two-parameter Weibull distribution to make it even more flexible in terms of its kurtosis coefficient. Properties involving moments and asymmetry and kurtosis indexes are studied.

Return period maps of dry spells for Catalonia (northeastern Spain) based on the Weibull distribution / Périodes de retour des périodes sèches en Catalogne (nord-est de l'Espagne) à partir de la distribution de Weibull [PDF]
Hydrological Sciences Journal, 2008 Abstract A detailed description of the spatial distribution of dry spell lengths in Catalonia (northeastern Spain) for the years 1950–2000 is obtained from a statistical analysis. The database is derived from the daily records of 75 raingauges, and a dry spell is defined as a set of consecutive days with daily rainfall amounts below thresholds of 0.1 ...

Journal of Renewable Energies, 2023 La situation énergétique au Bénin est caractérisée par un faible taux d’accès à l’électricité et une dépendance quasi-totale vis-à-vis de l’extérieur en énergie électrique. Sur la côte béninoise dans le Golfe de Guinée, on observe la propagation d’un vent quasi permanent et régulier.

The gamma-Weibull distribution revisited
Anais da Academia Brasileira de Ciências, 2010 The five parameter gamma-Weibull distribution has been introduced by Leipnik and Pearce (2004). Nadarajah and Kotz (2007) have simplified it into four parameter form, using hypergeometric functions in some special cases.
