Seminario di Nicolas Bousquet a Pavia
by Federico Bassetti 11 Sep '14

11 Sep '14

Venerdi' 19 settembre 2014, alle ore 11, presso l'aula Beltrami del Dipartimento di Matematica dell'Universita' degli Studi di Pavia (via Ferrata 1, Pavia) Nicolas Bousquet (EDF Research and Development, Dpt. of Industrial Risk Management, Chatou) terrà il seminario dal titolo *Some ideas about prior elicitation in Bayesian risk and reliability analysis* When dealing with small samples and large uncertainties in statistical risk and reliability analysis (typically when a highly reliable industrial component is studied, or when focusing on extreme events with the appropriate statistical theory), the help of Bayesian analysis, allowing to incorporate expert assessments based on technical knowledge, past ground experiments, meta-analyses.. , can be useful. Technically, it is needed to encode prior information into one or several statistical distributions. We review here some difficulties arising in practice, both technical and from the point of view of a control authority. Some methodological ideas about how eliciting a "good" prior are discussed, especially in the context where several sampling models can be compared (and their priors must be calibrated to do so). A major idea is speaking in terms of virtual data. Applications will deals with conjugate priors, some discrete models and Weibull, Gamma and extreme values models. Gli interessati sono invitati a partecipare. -- Federico Bassetti Dipartimento di Matematica, Universita' degli Studi di Pavia, Via Ferrata 1, 27100 Pavia, Italy E-mail federico.bassetti(a)unipv.it phone: +39 0382985633 // fax: +39 0382985602

Taniguchi's seminar at Bergamo University
by Ilia Negri 09 Sep '14

09 Sep '14

We are glad to invite you to the following seminar When: September 16th, 2014, 11:00 am Where: epartment of Management, Economics and quantitative Methods, Via dei Caniana n. 2 – Room 15 Title: Unified View of Portmanteau Tests for General Statistical Models Speacker: Masanobu TANIGUCHI Department of Applied Mathematics School of Science and Engineering Waseda University of Tokyo, Japan Abstract: This talk consists of the two parts (I) and (II). (I) Systematic Approach for Portmanteau Tests in View of Whittle Likelihood Ratio: Box and Pierce (1970) proposed a test statistic TBP which is the squared sum of m sample autocorrelations of the estimated residual process of autoregressive moving average model of order (p,q). TBP is called the classical portmanteau test. Under the null hypothesis that the autoregressive-moving average model of order (p,q) is adequate, they suggested that the distribution of TBP is approximated by chi-square distribution with (m-p-q) degrees of freedom, ”if m is moderately large”. This paper shows that TBP is understood as a special form of Whittle likelihood ratio test TPW for autoregressive-moving average spectral density with m-dependent residual process. Then, it is shown that, for any finite m, TPW does not converge to chi-square distribution with (m-p-q) degrees of freedom in distribution, and that, if we assume Bloomfield’s exponential spectral density TPW is asymptotically chi-square distributed for any finite m. From this observation we propose a natural Whittle likelihood ratio test TWLR which is always asymptotically chi-square distributed. Its local power is also evaluated. Numerical studies illuminate interesting features of TWLR. Because many versions of the portmanteau test have been proposed, and been used in variety of fields, our systematic approach for portmanteau tests and proposal of TWLR will give a unified view and useful applications. (II) A Unified View of Portmanteau Test for Diagnostic Checking : Here we construct a portmanteau test statistic TP as a sort of the likelihood ratio test for general statistical models based on the procedure given in (I). Then we derive sufficient conditions that the statistic is asymptotically chi-square distributed. Furthermore, it is shown that if a time series model whose spectral density has a product structure satisfies appropriate conditions, TP is asymptotically chi-square distributed. We also introduce a useful application of the test for variable selection.

By studying a dynamic asset allocation problem, we derive the optimal investment strategy in closed form and show that the combined momentum and reversal strategies are optimal. We then estimate the model to the S&P 500 and demonstrate that, by taking the timing opportunity with respect to trend in return and market volatility, the optimal strategies outperform not only pure momentum and pure mean reversion strategies, but also the market index and time series momentum strategy. Furthermore we show that the optimality also holds to the out-of-sample tests and short-sale constraints and the out performance is immune to market states, investor sentiment and market volatility.
