On the construction of balanced repeated measurements designs with good circular properties

open access: yesStatistical Theory and Related Fields, 2023
Several fields, such as biological, medical, public health, agricultural sciences, etc., require circular balanced repeated measurement designs with fewer unequal number of repeated measurements than the number of treatments.

Balanced Repeated Measurements Designs

open access: yesAnnals of Statistics, 1980
Two types of repeated measurements designs (RMD), the strongly balanced uniform RMD, and the balanced uniform RMD, are defined and their universal optimality is proved over very broad classes of competing designs. Construction methods for strongly balanced uniform RMD are also given.

Optimal Designs for Direct Effects: The Case of Two Treatments and Five Periods

open access: yesMathematics, 2023
Cross-Over Designs or Repeated Measurements Designs are experimental designs in which treatments (e.g., medicines, fertilizers, diets) are applied to experimental units (usually humans) in different time periods.

Repeated Measurements Designs. II. [PDF]

open access: yesThe Annals of Statistics, 1977
Abstract : Repeated measurements designs are concerned with scientific experiments in which subjects (experimental units) are repeatedly exposed to a sequence of different or identical tests (treatments). These designs have application in many branches of scientific inquiry such as: Biology, education, food science, marketing, environmental engineering,

Trend resistant designs for bioequivalence assessment of veterinary medicinal products

open access: yesIndian Journal of Animal Sciences, 2020
In veterinary medicinal trials, formulations are to be applied to the animals sequentially over time due to scarcity of homogeneous and healthy animals for experimentation, leading to carryover effects.

Repeated measures ASCA+ for analysis of longitudinal intervention studies with multivariate outcome data.

open access: yesPLoS Computational Biology, 2021
Longitudinal intervention studies with repeated measurements over time are an important type of experimental design in biomedical research. Due to the advent of "omics"-sciences (genomics, transcriptomics, proteomics, metabolomics), longitudinal studies ...

Gender differences in the mental health impact of the COVID-19 lockdown: Longitudinal evidence from the Netherlands

open access: yesSSM: Population Health, 2021
Recent contributions highlighted gender differences in the mental health consequences of COVID-19 lockdowns. However, their cross-sectional designs cannot differentiate between pre-existing gender differences and differences induced by lockdowns ...
