Paquete creado con el fin de facilitar el cálculo y distribución del à ndice Socio Material Territorial (ISMT), elaborado por el Observatorio de Ciudades UC. La metodologà a completa está disponible en "ISMT" (<https://ideocuc-ocuc.hub.arcgis.com/datasets/6ed956450cfc4293b7d90df3ce3474e4/about>) [Observatorio de Ciudades UC (2019)]. || Package created to facilitate the calculation and distribution of the Socio-Material Territorial Index by Observatorio de Ciudades UC. The full methodology is available at "ISMT" (<https://ideocuc-ocuc.hub.arcgis.com/datasets/6ed956450cfc4293b7d90df3ce3474e4/about>) [Observatorio de Ciudades UC (2019)].

Four global value chain (GVC) decompositions of gross exports from inter-country input-output tables are implemented. The Leontief decomposition derives the value added origin of exports by country and industry, as in Hummels, Ishii and Yi (2001) <doi:10.1016/S0022-1996(00)00093-3>. The Koopman, Wang and Wei (2014) <doi:10.1257/aer.104.2.459> decomposition splits country-level exports into 9 value added components, and the Wang, Wei and Zhu (2013) <doi:10.3386/w19677> decomposition splits bilateral exports into 16 value added components. The Borin and Mancini (2019) <doi:10.1596/1813-9450-8804> decomposition splits country-, sector- or bilateral-level exports into up to 13 value added and GVC components, and also provides a corrected version of the (biased) Koopman-Wang-Wei decomposition. It is the recommended method and reproduces the icio command for Stata described in Belotti, Borin and Mancini (2021) <doi:10.1177/1536867X211045573>.

Simulation of the random evolution of heterogeneous populations using stochastic Individual-Based Models (IBMs) <doi:10.48550/arXiv.2303.06183>. The package enables users to simulate population evolution, in which individuals are characterized by their age and some characteristics, and the population is modified by different types of events, including births/arrivals, death/exit events, or changes of characteristics. The frequency at which an event can occur to an individual can depend on their age and characteristics, but also on the characteristics of other individuals (interactions). Such models have a wide range of applications. For instance, IBMs can be used for simulating the evolution of a heterogeneous insurance portfolio with selection or for validating mortality forecasts. This package overcomes the limitations of time-consuming IBMs simulations by implementing new efficient algorithms based on thinning methods, which are compiled using the Rcpp package while providing a user-friendly interface.

Intensity-duration-frequency (IDF) curves are a widely used analysis-tool in hydrology to assess extreme values of precipitation [e.g. Mailhot et al., 2007, <doi:10.1016/j.jhydrol.2007.09.019>]. The package IDF provides functions to estimate IDF parameters for given precipitation time series on the basis of a duration-dependent generalized extreme value distribution [Koutsoyiannis et al., 1998, <doi:10.1016/S0022-1694(98)00097-3>].
