Statistical process monitoring to improve quality assurance of inpatient care
BMC Health Services Research, 2020 Background Statistical Process Monitoring (SPM) is not typically used in traditional quality assurance of inpatient care. While SPM allows a rapid detection of performance deficits, SPM results strongly depend on characteristics of the evaluated process.

The taTME learning curve for mid-low rectal cancer: a single-center experience in China
World Journal of Surgical Oncology, 2022 Purpose As transanal total mesorectal excision (taTME) is performed worldwide, the optimization of existing training and guidance programs to enhance new taTME learners’ competence in performing this procedure is warranted.

Location and scale-based CUSUM test with application to autoregressive models
Journal of Statistical Computation and Simulation, 2020 This study aims to refine the residual cumulative sum (CUSUM) test for location-scale time series and to develop the location and scale-based CUSUM (LSCUSUM) test. This test clarifies the role of residuals in the CUSUM test well. In addition, it provides

Power of change-point tests for long-range dependent data [PDF]
, 2017 We investigate the power of the CUSUM test and the Wilcoxon change-point tests for a shift in the mean of a process with long-range dependent noise. We derive analytic formulas for the power of these tests under local alternatives.

Environmental boundary tracking and estimation using multiple autonomous vehicles [PDF]
, 2008 In this paper, we develop a framework for environmental boundary tracking and estimation by considering the boundary as a hidden Markov model (HMM) with separated observations collected from multiple sensing vehicles.

Data-Efficient Minimax Quickest Change Detection with Composite Post-Change Distribution [PDF]
, 2014 The problem of quickest change detection is studied, where there is an additional constraint on the cost of observations used before the change point and where the post-change distribution is composite. Minimax formulations are proposed for this problem.

The Cusum Median Chart for Known and Estimated Parameters
Revstat Statistical Journal, 2019 The usual CUSUM chart for the mean (CUSUM-X¯) is a chart used to quickly detect small to moderate shifts in a process. In presence of outliers, this chart is known to be more robust than other mean-based alternatives like the Shewhart mean chart but it ...

Asymptotic Distribution of the Delay Time in Page's Sequential Procedure
, 2013 In this paper the asymptotic distribution of the stopping time in Page's sequential cumulative sum (CUSUM) procedure is presented. Page as well as ordinary cumulative sums are considered as detectors for changes in the mean of observations satisfying a ...

Univariate mean change point detection: Penalization, CUSUM and optimality [PDF]
Electronic Journal of Statistics, 2018 The problem of univariate mean change point detection and localization based on a sequence of $n$ independent observations with piecewise constant means has been intensively studied for more than half century, and serves as a blueprint for change point ...
