Extending Local Canonical Correlation Analysis to Handle General Linear Contrasts for fMRI Data

Figure 3

Distributions of the proposed CCA statistic (“cCCA-RG novel”) along with the conventional 𝑡-statistic used in the GLM using resampled resting-state data and contrast E-C for the memory paradigm. The difference of the GLM-based 𝑡-statistic from a theoretical 𝑡-distribution (blue solid curve, DOF = 278) was mainly caused by the temporal correlation in fMRI signal. The novel CCA statistic has the widest profile because of the additional spatial modeling.
