26 p, 426.3 KB Empirical analysis of daily cash flow time-series and its implications for forecasting / Salas-Molina, Francisco (Universitat de València) ; Rodríguez Aguilar, Juan Antonio (Institut d'Investigació en Intel·ligència Artificial (IIIA-CSIC)) ; Serra Sagristà, Joan (Telefónica Research (Barcelona, Catalunya)) ; Guillén, Montserrat (Universitat de Barcelona. Departament d'Econometria) ; Martin, Francisco J. (BigML, Inc. (Corvallis, Estats Units d'Amèrica))
Usual assumptions on the statistical properties of daily net cash flows include normality, absence of correlation and stationarity. We provide a comprehensive study based on a real-world cash flow data set showing that: (i) the usual assumption of normality, absence of correlation and stationarity hardly appear; (ii) non-linearity is often relevant for forecasting; and (iii) typical data transformations have little impact on linearity and normality.

24 p, 434.0 KB Using a Bayesian change-point statistical model with autoregressive terms to study the monthly number of dispensed asthma medications by public health services / Mota de Queiroz, J. A. (Instituto Federal do Paraná – IFPR (Brasil)) ; Aragon, Davi Casale (Universidade de São Paulo. Ribeirão Preto Medical School) ; Mello, Luane Marques de (Universidade de São Paulo. Ribeirão Preto Medical School) ; Previdelli, Isolde Terezinha Santos (Universidade Estadual de Maringá) ; Martinez, Edson Z. (Universidade de São Paulo. Ribeirão Preto Medical School)
In this paper, it is proposed a Bayesian analysis of a time series in the presence of a random change-point and autoregressive terms. The development of this model was motivated by a data set related to the monthly number of asthma medications dispensed by the public health services of Ribeirao Preto, Southeast Brazil, from 1999 to 2011.

6 p, 3.6 MB Scoring coordination patterns in basketball international championships of national teams / Prieto Bermejo, Jaime (Universidad Complutense de Madrid) ; García Rubio, Javier (Universidad Autonoma de Chile. Facultad de Educación) ; Ibáñez Godoy, Sergio José (Universidad de Extremadura. Facultad de Ciencias del Deporte)
The performance of two basketball teams can be analysed by exploring their different scoring dynamics on the basis of the two time series representing the scoring process of each team throughout the game. [...]

28 p, 700.0 KB Using robust FPCA to identify outliers in functional time series, with applications to the electricity market / Vilar, Juan M. (Universidade da Coruña. Departamento de Matemáticas) ; Raña, Paula (Universidade da Coruña. Departamento de Matemáticas) ; Aneiros, Germán (Universidade da Coruña. Departamento de Matemáticas)
This study proposes two methods for detecting outliers in functional time series. Both methods take dependence in the data into account and are based on robust functional principal component analysis. [...]

46 p, 511.8 KB Multilinear singular integrals / Thiele, Christoph M. (University of California. Department of Mathematics)
We survey the thoery of multilinear singular integral operators with modulation symmetry. The basic example for this theory is the bilinear Hilbert transform and its multilinear variants. We outline a proof of boundedness of Carleson's operator which shows the close connection of this operator to multilinear singular integrals. [...]
