E
- Exchangeable Correlation
- A correlation structure for repeated measures assuming any two observations within the same cluster are equally correlated, regardless of their timing or order.
G
- Generalized Estimating EquationsGEE
- A method analysing repeated measures or clustered data, estimating population-average effects while accounting for within-cluster correlation, without a full random effects specification.
M
- Mixed Model Analysis
- The application of a mixed effects framework, combining fixed and random effects, to analyse data with a repeated measures or hierarchical structure.
- Mixed Model Repeated Measures
- A longitudinal trial analysis method using a mixed effects framework under the missing at random assumption, an alternative to last observation carried forward.
R
- Repeated Measures
- A study design in which the same outcome is measured multiple times on the same individuals, typically at different points in time.
- Repeated Measures Analysis
- A statistical approach analysing data in which the same outcome has been measured multiple times on the same individuals, accounting for correlation.
U
- Unstructured Correlation
- A correlation structure for repeated measures allowing the correlation between every pair of time points to be estimated freely and independently.
