Needs["MultivariateStatistics`"]Total variation is equivalent to the trace of the covariance matrix:
TotalVariation[{{1, 0}, {0, 2}, {3, 4}, {4, 2}}]Tr[Covariance[{{1, 0}, {0, 2}, {3, 4}, {4, 2}}]]Total variation is equivalent to the sum of column variances:
Total[Variance[{{1, 0}, {0, 2}, {3, 4}, {4, 2}}]]
