Exponentially Weighted Moving Average Control Schemes for Assessing Hospital Organizational Performance

Statistica, 2016
Exponentially weighted moving average (EWMA) control charts have been successfully used in recent years in several areas of healthcare. Most of these applications have concentrated on the problem of detecting shifts in the mean level of a process.

Audit‐Ready Machine Learning for Short‐Horizon Equity Prediction: A Dual‐Target Benchmark With Fold‐Isolated Preprocessing

Engineering Reports, Volume 8, Issue 6, June 2026.
This study introduces a rigorous, walk‐forward protocol to evaluate next‐day return and volatility‐proxy forecasting across matched model families. By enforcing fold‐isolated preprocessing and causal feature construction on US mega‐caps, the study eLectively mitigates performance inflation.

Windowed Mean Drift Exponentially Weighted Moving Average Control Chart for Monitoring Complex Autocorrelated Processes

Quality and Reliability Engineering International, Volume 42, Issue 4, Page 1691-1706, June 2026.
ABSTRACT In modern manufacturing environments, traditional statistical process control (SPC) methods often struggle with complex, dynamic data patterns, particularly when observations are autocorrelated. Control charts are useful tools used in SPC to detect any significant drift in a process.

Staff Perspectives on Non‐Routine Compression Therapy for Inpatients With Venous Leg Ulcers: A Qualitative Study

International Wound Journal, Volume 23, Issue 6, June 2026.
ABSTRACT Compression therapy is the evidence‐based treatment for healing venous leg ulcers. However, it is not routinely applied in many UK hospitals. This paper explores hospital staff's' perspectives of venous leg ulcer care provision where compression therapy is not routinely applied.

Multivariate statistical process control for daily linear accelerator quality assurance: A framework for early detection and diagnosis

Medical Physics, Volume 53, Issue 5, May 2026.
Abstract Background Statistical Process Control (SPC) has gained increasing interest in radiotherapy Quality Assurance (QA), particularly following recommendations from American Association of Physicists in Medicine Task Group 218. However, SPC is still predominantly applied via univariate charts such as Shewhart and Exponentially Weighted Moving ...
