Shared and Data-specific variation for cell-cycle data. Shared (top) and data-specific (bottom) variation retained with CCA (solid line) and PCA (dashed line) as a function of reduced dimensionality for the cell-cycle data. The values obtained by random projections (dash-dotted line and dotted confidence intervals) have been included for reference. The suggested dimensionality for the CCA-projection is marked with a tick.
