Similar results were achieved while taking a source covariance matrix as an identity matrix [8, 9].
More recently, [ 8] propose a MANOVA test using a shrinkage covariance matrix estimator for the sample covariance matrix.
Then, the covariance structure of the data was modelled using a exponential covariance function with a range value of θ = 0.24 and a nugget of α = 0.35.
The FAC (Figure 4) is based on χ2 distances using a covariance matrix.
The analyses used a mixed model approach: 'within-animal' correlations were modelled using a compound symmetric covariance structure (which assumes sphericity of the variance/covariance matrix).
Time was fitted as a repeated effect using a heterogeneous autoregressive covariance structure.
In our study, confidence intervals were calculated using a variance-covariance matrix on the fitted parameters.
