Repeated Measures ANOVA - Stony Brook

As with any ANOVA, repeated measures ANOVA tests the equality of means. However, repeated measures ANOVA is used when all members of a random sample are measured under a number of different conditions or at different time points. As the sample is exposed to each condition, the measurement of the dependent variable is repeated.

Repeated measures analysis with R

Repeated measures analysis with R Summary for experienced R users The lmer function from the lme4 package has a syntax like lm. Add something like + (1|subject) to the model for the random subject effect. To get p-values, use the car package. Avoid the lmerTest package.

Mixed Model Repeated Measures (MMRM)

What is Repeated Measure? Measured at fixed time points Serial evaluation over time on the same patient THESE MEASUREMENTS CANNOT BE CONSIDERED AS INDEPENDENT. Measurements over multiple visits, known as ‘longitudinal’ data over time.
