Quality analysis of BCG vaccine for bladder cancer immunotherapy using Shewhart control charts
Биопрепараты: Профилактика, диагностика, лечениеSCIENTIFIC RELEVANCE. The complexity of standardising immunobiologicals, including bacillus Calmette–Guérin (BCG) vaccines, requires improving the approach to statistical analysis of consistency in their quality indicators. Quality analysis tools include

Pharmaceutical Statistics, Volume 24, Issue 2, March/April 2025.ABSTRACT In pre‐clinical and medical quality control, it is of interest to assess the stability of the process under monitoring or to validate a current observation using historical control data. Classically, this is done by the application of historical control limits (HCL) graphically displayed in control charts. In many applications, HCL are applied

Shewhart’s Control Chart: Some Observations
, 1999 Data Analysis in Shewhart’s Control Chart, to use the original m samples n sized intensities, is the main subject of this paper. Given m × n intensities we examine three alternatives to sintetize the variability: a) arithmetic mean of m standard deviations (' S); b) root mean square of m variances (" S); c) global dispersion ("" S).

Internal Medicine Journal, Volume 55, Issue 2, Page 308-312, February 2025.ABSTRACT General physicians as system leaders play a significant role in quality improvement (QI) initiatives within respective health services. However, there are very few formal QI training programmes available for general physicians in Australia. This survey described the experiences of attendees at the 2024 Internal Medicine Society of Australia ...

A new procedure for monitoring the range and standard deviation of a quality characteristic [PDF]
The Shewhart and the Bonferroni-adjustment R and S chart are usually applied to monitor the range and the standard deviation of a quality characteristic. These charts are used to recognize the process variability of a quality characteristic.

General adapted‐threshold monitoring in discrete environments and rules for imbalanced classes
Statistica Neerlandica, Volume 79, Issue 1, February 2025.Having in mind applications in statistics and machine learning such as individualized care monitoring, or watermark detection in large language models, we consider the following general setting: When monitoring a sequence of observations, Xt, there may be additional information, Zt, on the environment which should be used to design the monitoring ...

Control Charts for the Lognormal Distribution [PDF]
Control Charts are the main tools of Statistical Process Control. They are used for deciding whether a process is statistically stable or not. Much theory and many applications have been developed for the Gaussian (Normal) distribution in this area ...
