BiweightMidvariance

BiweightMidvariance[list] gives the value of the biweight midvariance of the elements in list.

BiweightMidvariance[list, c] gives the value of the biweight midvariance with scaling parameter c.

Examples

Robust variance estimate:

BiweightMidvariance[{1, 2, 3, 4, 100}]

Compare with standard variance:

{BiweightMidvariance[{1, 2, 3, 4, 5}], Variance[{1, 2, 3, 4, 5}]}
