We construct a Generalized p value for testing statistical hypotheses on the comparison of mean vectors in the sequential observation of two continuous time multidimensional Gaussian processes. The mean vectors depend linearly on two multidimens[...]texto impreso
Fenoy, Mar ; Gámez Merino, José Luis ; Muñoz-Fernández, Gustavo A. ; Sáez Maestro, Eva | De Gruyter Open Ltd | 2017This expository paper focuses on the study of extreme surjective functions in ??. We present several different types of extreme surjectivity by providing examples and crucial properties. These examples help us to establish a hierarchy within the[...]texto impreso
Conejero, Jose A. ; Fenoy, Mar ; Murillo Arcila, Marina ; Seoane-Sepúlveda, Juan B. | Springer Milan | 2017The search of lineability consists on finding large vector spaces of mathematical objects with special properties. Such examples have arisen in the last years in a wide range of settings such as in real and complex analysis, sequence spaces, lin[...]texto impreso
Escobar, Daniela ; Fenoy, Mar ; Luna, M. Y. ; Martin, M. A. ; Morata, A. ; Pascual, A. | Copicentro | 2014The longest time series of precipitation in San Fernando, Cadiz will be analized. The avaiable data is from January of 1851 to December of 2008. The goal is to fit a model and estimate the parameters in order to predict future values of the time[...]texto impreso
Los problemas de decisión secuencialmente planificados, son problemas secuenciales en los que en cada etapa no solo se decide si para o continuar con el muestreo, sino en este último caso cual es el tamaño muestral de la siguiente submuestra, y [...]texto impreso
In this paper we generalize classical results about sufficiency in the sequential decision theory to sequentially planned decision procedures. We obtain the completeness of the class of decision rules based on the sufficient a-fields family. The[...]texto impreso
We define the invariant sequentially planned decision procedure under a group of measurable transformations. By means of a previous reduction of the problem, we obtain the optimal invariant sequentially planned decision procedure that minimizes [...]texto impreso
The optional sampling theorem is considered in the sequentially planned context. We prove the optional sampling theorem for direct successors and for sampling plans with a finite number of stages. Also, the theorem is studied in the general case[...]
