Evaluation of a non‐radioactive rapid test for determination of serum progesterone in South American camelids

Veterinary Record, EarlyView.
Abstract Background Determination of the serum progesterone (P4) concentration is of high importance in reproductive medicine and may be applied for diagnosing pregnancy in South American camelids. P4 measurements in alpacas and llamas are usually performed using immunoassays, which are time consuming and require appropriate expertise of laboratory ...

Comparing risk-adjusted and unadjusted CUSUM monitoring in Dutch liver procurement quality control: Evaluating the potential in a retrospective setting

Heliyon
Background: Risk-adjusted CUSUM outcome monitoring adjusts for risk factors that may influence alarm signaling in heterogeneous datasets. This study aimed to compare risk-adjusted and unadjusted CUSUM graphs for iatrogenic injury and discard rates in ...

Detection of multiple change points for linear processes under negatively super-additive dependence

Journal of Inequalities and Applications, 2019
This paper focuses on the issue of detecting the multiple change points for linear processes under negatively super-additive dependence (NSD). We propose a CUSUM-type method in the multiple variance change model and establish the weak convergence rate of

COMPARISON BETWEEN TWO METHODS OF SURVEILLANCE: EXPONENTIALLY WEIGHTED MOVING AVERAGE VS CUSUM

, 1993
When control charts are used in practice it is necessary to know the characteristics of the charts in order to know which action is appropriate at an alarm.

A Note on Local Polynomial Regression for Time Series in Banach Spaces

Journal of Time Series Analysis, EarlyView.
ABSTRACT This work extends local polynomial regression to Banach space‐valued time series for estimating smoothly varying means and their derivatives in non‐stationary data. The asymptotic properties of both the standard and bias‐reduced Jackknife estimators are analyzed under mild moment conditions, establishing their convergence rates.

New Cumulative Sum Control Chart for Monitoring Poisson Processes

IEEE Access, 2017
The cumulative sum (CUSUM) control charts are widely used for measurement control of continuous processes. However, the quality characteristics of interest in many production processes, follows a sequence of discrete counts for non-conformities often ...
