Contributions to Profile Monitoring and Multivariate Statistical Process Control
… distribution for the T² statistic based on the successive differences covariance matrix estimator. Part 1: Nonlinear Profile Monitoring In an increasing number of cases the quality of a product or process cannot adequately be represented by the distribution of a univariate quality variable or …

Analysis of affective instability on ecological momentary assessments data: successive difference, variance decomposition, and mean comparison via multilevel modeling
… temporal instability are proposed: Mean squared successive differences (MSSD) and probability of acute change (PAC). Additionally, resiudalizing scores by controlling time effects, such as long-term trend or diurnal effect, at the individual level is useful for identifying artifactual sources of …

Controlling for Acute Caffeine Intake in Cardiovascular Reactivity Research
… rate variability (hfHRV), root mean squared successive differences (RMSSD), systolic and diastolic blood pressures (SBP, DBP), mean arterial pressure (MAP), pre-ejection period (PEP), left ventricular ejection time (LVET), and total peripheral resistance (TPR). Results support the adequacy of …

NBA Sleep Tracking Data Imputation
… sleep duration, rMSSD (Root Mean Square of the Successive Differences between Heartbeats), and average heart rate. Results indicate K-Nearest Neighbors Regression and Linear Interpolation, with access to data in the past and future (offline imputation), as the best-performing sleep imputation …

Modeling the Impact of Heart Rate Variability on Blood Pressure in Simulated Atrial Fibrillation Using the BioGears Physiology Engine
… during AF, quantified by the root mean square of successive differences (RMSSD), influences beat-to-beat hemodynamic stability. Synthetic RR interval sequences were generated to span a physiological AF RMSSD range (80–250 ms) and imposed onto the BioGears cardiovascular model across ten virtual …

The Relation of Heart Rate Variability and Body Weight Change in Conducting Community-based Obesity Control Program
… N-N interval (SDNN), RMSSD (Root-Mean-Square of Successive Differences), Total Power (TP), Low Frequency(LF), High Frequency (HF), LF/HF ratio를 측정하였다. 비만 치료는 정형화된 식사요법과 운동, 행동교정을 병행하였다. 비만 치료 12주 후에 신체 검사 및 혈액 검사를 다시 하여 그 변화 정도와 기저 HRV와 비교하였다. 결과: 총 102명의 대상자 중 96명이 여성이었고, 기저 심박동수 변이는 교감신경계 활성도를 …

Developing a Digital Sustainability Framework for Interior Construction Projects: A Stakeholder-Centred Digital Platform for Sustainable Decision-Making and Biophilic Integration
… HRV indices included the root mean square of successive differences (RMSSD) and the low frequency/high frequency ratio (LF/HF), capturing parasympathetic activity and autonomic balance. Waterscapes containing dynamic or biotic elements yielded the most consistent restorative benefits. …

Profile Monitoring with Fixed and Random Effects using Nonparametric and Semiparametric Methods
… estimated variance-covariance matrix based on successive differences. A Monte Carlo study was performed to compare the integrated mean square errors (IMSE) and the probability of signal of the parametric, nonparametric, and semiparametric approaches. Both correlated and uncorrelated errors …
