OBJECTIVES To evaluate short-term effects of publishing revised lower risk national drinking guidelines on related awareness and knowledge. To examine where drinkers heard about guidelines over the same period. DESIGN Trend analysis of the Alcohol Toolkit Study, a monthly repeat cross-sectional national survey. SETTING England, November 2015 to May 2016. PARTICIPANTS A total of 11 845 adu...

In this paper, a new control chart to monitor multi-binomial processes is first proposed based on a transformation method. Then, the maximum likelihood estimators of change points designed for both step changes and linear-trend disturbances are derived. At the end, the performances of the proposed change-point estimators are evaluated and are compared using some Monte Carlo simulation experimen...

Abstract We propose TrendSegment, a methodology for detecting multiple change-points corresponding to linear trend changes in one dimensional data. A core ingredient of TrendSegment is new Tail-Greedy Unbalanced Wavelet transform: conditionally orthonormal, bottom-up transformation the data through an adaptively constructed unbalanced wavelet basis, which results sparse representation Due its n...

The Sj-test proposed by Noether [7] is a sequentialtest of the hypothesis of randomness against the alter-native of linear trend, which can be expressed as thehypothesis that the joint distribution of xl, x2, ••• , lhis given byifi=lThe Sj-test is carried out by comparing Xi with Xi+j' forfixed j ~ o, and using the sequential probability ratiotest of the hypo...
