If the data are stationary, reversible and r=1 this is equivalent to the GMRQ. With r=2 this expression measures the kinetic variance 51 captured by the basis sets. The VAMP scores have also been adapted to score the models based on the type of feature alone (rather than scoring the full MSM). As timescales are monotonic functions of the eigenvalues, maximizing the sum of the timescales also maximizes the VAMP scores.
