El conjunto de datos está formado por series precipitación mensual de la Península Ibérica y las Islas Baleares. Aparecen diferencias no sólo en los análisis wavelet continuo y discreto, sino también los resultados son distintos para distintas zonas de la Península. Como consecuencia de esto se ha dividido el territorio peninsular en dos regiones: la región Atlántica y la región Mediterránea y se ha realizado el análisis continuo y discreto en ambas. Se pueden observar fuertes diferencias en la intensidad de los coeficientes wavelet en las dos regiones, así como en la variabilidad que muestran. En la región Mediterránea aparecen variaciones más intensas para grandes escalas temporales mientras que en la región Atlántica las escalas tempo...

Aparecen diferencias no solo en los analisis wavelet continuo y discreto, sino tambien los resultados son distintos para distintas zonas de las Peninsula. Como consecuencia de esto se ha divido el territorio peninsular en dos regiones: la region Atlantica y la region Mediterranea y se ha realizado el analisis continuo y discreto en ambas. En la region Mediterranea aparecen variaciones mas intensas para grandes escalas temporales mientras que en la region Atlantica las escalas temporales mas destacadas son mas cortas.

Research paper thumbnail of Extended Homogeneous Processes and Bayes Estimation of Reliability Functions

Extended homogeneous prncesses are defined whose sample paths may be assumed to be increasing hazai•d rates by properly choosing the parameter functions of the processes. Estimators are obtained in the mentioned processes and their asymptotic properties are studied. An application for simulated dada is given.

In this paper, we have derived some standard inequalities from the mean of order ttt and studied some interesting properties of Box and Cox's transformation function. A compos- iterelation of these two measures, calling generalized mean of order ttt or unified (t,s)(t,s)(t,s)-mean is considered. The unified (t,s)(t,s)(t,s)-mean leads us to very important gen- eralized information theoretic measures. These measures include generalizations of Shannon's entropy, Kullback-leibler's relative information, Kerridge's inaccu- racy, J-divergence, Jensen difference dive~gence measure, etc. Properties of unified (t,s)(t,s)(t,s)-mean are also studied.

After studying some of its properties, the expression obtained in sampling from step)1 to step n + 1 is given, and its bayesian properties are investigated. We also establish the "good behavior" of a stopping rule, defined on the basis of the information obtained in sampling, when passing from one step to the next.
