Abstract: In some situations, theoreticians recommend a given predictive model for a series of financial time. However, some inappropriate behaviors in given series make such a model unsuitable. One of the reasons for this can be the non-linearity of those behaviors. A proposed model to treat these series is the TAR model (threshold autoregressive). TAR models are determined by a variable called threshold for which it mainly results to be a temporal nonlinear model. A TAR model expresses itself as a temporal series, with a lagged as a threshold variable, where d is an entire positive called retard threshold. In practice, the threshold variable is unknown, due to which an important question is how to determine it; an answer to this question is given in this paper. TAR models are illustrated by modeling Spain\\\\\\\\\\\\\\\'s Gross Domestic Product.
In this paper, we propose an algorithm, RI-Maps, that combines fractal theory, stochastic calculus and computational geometry for simulating realistic irregular lattices with a predefined number of polygons.
The dropout rate among Spanish university students is very high compared to the European mean, creating a pressing need for the introduction of policies and programmes aimed at increasing rates of persistence.
