WebNov 25, 2016 · 3. The answer depends on the hypothesis/-es you want to test. If you simply want to know if activity at either of these time points correlates with reaction time, then you should compute two separate correlations. You could then make statements like "reaction time is significantly correlated with y1, but not with y2". WebIf you are looking repeated measures, you are looking a paired t-test case. Basically you need to apply this formula: t* sqrt [ (2 (1-r)/n)] where r is the correlation coefficient between the two ...

WebRepeated measures anova assumes that the within-subject covariance structure has compound symmetry. There is a single variance (σ 2) for all 3 of the time points and there is a single covariance (σ 1 ) for each of the pairs of trials. This is illustrated below. Stata calls this covariance structure exchangeable. WebJul 31, 2013 · The unstructured correlation pattern assumes there are no particular correlation patterns among the repeated measures. Each correlation between any two repeated measurements may be unique.
