Este trabajo final de maestria, modalidad de profundizacion, consiste en la elaboracion de un problema de modelacion estadistica aplicada al sector crediticio. El objetivo es aplicar un modelo de regresion logistica o un modelo de aprendizaje de maquina para calcular la probabilidad de default e incorporarla en la formula para hallar la distribucion de costos totales en el modelo de Mezclas Bernoulli, con el fin de estimar valores de cuartiles superiores de la distribucion de los costos totales,...

El presente trabajo aborda el problema de seleccion de variables empleando el metodo de bosques aleatorios cuando el modelo subyacente para la variable respuesta es de tipo lineal. Para ello se configuran conjuntos de datos simulados con diferentes caracteristicas, sobre los cuales se aplica la metodologia y se mide el error de prediccion al eliminar cada variable. Con esto se realiza en primera instancia, una evaluacion del algoritmo de seleccion en la que se identifica que este es eficiente cu...

Abstract In highly productive farmlands, field margins could offer habitats and refuges for many plant and animal species. But species-rich field margins are rapidly declining due to field enlargements and unfavourable management practices. In European farmland, management is usually restricted to repeated mulching during the growing season or mulching once a year between September and February. Under nutrient-rich conditions, both methods benefit competitive perennial grasses at the expense of ...

1. Predicting restoration outcomes requires an understanding of the natural variability of ecosystem properties. A hierarchy of predictability has been proposed that ranks measures of restoration success from most-to-least predictable in the following order: vegetation structure > taxonomic diversity > functional diversity > taxonomic composition. This hierarchy has not been tested empirically, and the location within the hierarchy of trait-based measures, such as community-level trait means and...

Summary Ecological restoration is a global priority that holds great potential for benefiting natural ecosystems, but restoration outcomes are notoriously unpredictable. Resolving this unpredictability represents a major, but critical challenge to the science of restoration ecology. In an effort to move restoration ecology toward a more predictive science, we consider the key issue of variability. Typically, restoration outcomes vary relative to goals (i.e. reference or desired future conditions...

Questions (1) When alpine vegetation is actively restored by seeding, how is vegetation cover influenced by seeding treatments and soil conditions? (2) How does the cover of species differ when they are seeded in a mixture and how is their response influenced by soil conditions? (3) Do individual species perform better or worse in a mixture than when sown separately? Location Hjerkinn, Dovrefjell, Norway. Methods In a factorial, randomized field experiment, we recorded the percentage cover of Fe...

Ecological restoration is widely practiced as a means of rehabilitating ecosystems and habitats that have been degraded or impaired through human use or other causes. Restoration practices now are confronted by climate change, which has the potential to influence long-term restoration outcomes. Concepts and attributes from the resilience literature can help improve restoration and monitoring efforts under changing climate conditions. We systematically examined the published literature on ecologi...

Within the varied contexts of environmental policy, conservation of imperilled species populations, and restoration of damaged habitats, an emphasis on idealized optimal conditions has led to increasingly specific targets for management. Overly-precise conservation targets can reduce habitat variability at multiple scales, with unintended consequences for future ecological resilience. We describe this dilemma in the context of endangered species management, stream restoration, and climate-change...

Restoration is important for biodiversity conservation worldwide, but surprisingly little is known about its efficiency in a long-term perspective. In this study, we re-examined Swedish semi-natural grasslands 12–20 years after the restoration, by comparing field inventories of vascular plant species diversity made in 2001 with follow-up inventories in 2012. We also analysed restoration effect in relation to six environmental factors and used continuously managed semi-natural grasslands as refer...

Temperate woodlands are one of the world's ecosystems in greatest need of ecological restoration, but relatively little is known about their floristic recovery dynamics over decadal timescales. From 2000 to 2012, we monitored understory plant communities in a woodland mosaic in Missouri, USA, as it underwent restoration via prescribed, dormant-season burning and mechanical thinning of red cedar (Juniperus virginiana) and exotic shrubs. Native species richness increased linearly by 36% over this ...
