Trend or no trend : a novel nonparametric method for classifying time series
… approach by applying it to the task of detecting trending topics on Twitter. Using a small sample of Tweets, our method can detect trends before Twitter does 79% of the time, with a mean early advantage of 1.43 hours, while maintaining a 95% true positive rate and a 4% false positive rate. In …

Reliability Trend Analyses With Statistical Confidence Limits Using the Luke Reliability Trend Chart
<p>In electronic systems, it is interesting to understand exactly how the reliability is changing with time. Dynamic performance changes when a system passes from infant mortality stage into useful life phase and when the system passes from useful life phase into wearout phase. Dynamic performance …

Suicide Terrorism: A Future Trend?
This thesis reviews the literature on “new terrorism,” to be differentiated from the “old terrorism.” The study tests two hypotheses. First, has an increase in religiously inspired terrorist groups led to an increase in terrorism's lethality? Second, does suicide bombing as a tactic explain the …

Comparison of Trend Detection Methods
Trend estimation is important in many fields, though arguably the most important applications appear in ecology. Trend is difficult to quantify; in fact, the term itself is not well-defined. Often, trend is quantified by estimating the slope coefficient in a regression model where the response …

Discovery of trend dependencies over time-series
We improve constraint-based data quality using trend dependency (TD) discovery, extending existing order dependencies (ODs) to allow variations and exceptions. Unlike ODs, TDs capture approximate functional mappings between attributes, addressing the limitations of monotonicity. Our approach …
