We explore a new dimension of fund managers' timing ability by examining whether they can time market liquidity through adjusting their portfolios'market exposure as aggregate liquidity conditions change. Using a large sample of hedge funds, we find strong evidence of liquidity timing. A bootstrap analysis suggests that top-ranked liquidity timers cannot be attributed to pure luck. In out-of-sa...

We propose a methodology to study music development by applying multivariate statistics on composers characteristics. Seven representative composers were considered in terms of eight main musical features. Grades were assigned to each characteristic and their correlations were analyzed. A bootstrap method was applied to simulate hundreds of artificial composers influenced by the seven represent...

Residual-based analysis is generally considered a cornerstone of statistical methodology. For a special case of indirect regression, we investigate the residual-based empirical distribution function and provide a uniform expansion of this estimator, which is also shown to be asymptotically most precise. This investigation naturally leads to a completely data-driven technique for selecting a reg...

Goodness-of-fit and symmetry tests are proposed for the innovation distribution in generalized autoregressive conditionally heteroscedastic models. The tests utilize an integrated distance involving the empirical characteristic function (or the empirical Laplace transform) computed from properly standardized observations. A bootstrap version of the tests serves the purpose of studying the small...

We propose a method for compiling bilingual terminologies of multi-word terms (MWTs) for given translation pairs of seed terms. Traditional methods for bilingual terminology compilation exploit parallel texts, while the more recent ones have focused on comparable corpora. We use bilingual corpora collected from the web and tailor made for the seed terms. For each language, we extract from the c...

In this paper we investigate the impact of the switching from the same-day settlement to the following-day settlement on the market volatility and its structure. Using the Levene tests and bootstrap procedures, we find that the switching causes a drastic decrease in the stock market volatility. In addition, using a modified GARCH model, we also find a substantial change in the volatility struct...

Association rule discovery in large data sets is vulnerable to producing excessive false positives, due to the multiple inference effect. This paper first sets this issue in precise mathematical terms and presents some analytical results. These show that a common concern regarding effects of filtering is not as problematic as had been previously thought. The analytical results also shed new lig...

The aim of this paper is to point out some problems of index estimation for the purposes of weather derivative valuation considering the particularities of agriculture. The assessment of the sensitivity of barley to weather over 40 years has been the basis for the design and valuation of weather derivative in the Czech Republic (The Southern Moravia Region). The analysis is based on regression ...
