statsmodels.tools.eval_measures.medianbias

statsmodels.tools.eval_measures.medianbias(x1, x2, axis=0)[source]

median bias, median error

Parameters:
  • x2 (x1,) – The performance measure depends on the difference between these two arrays.
  • axis (int) – axis along which the summary statistic is calculated
Returns:

medianbias – median bias, or median difference along given axis.
Return type:

ndarray or float

Notes

If x1 and x2 have different shapes, then they need to broadcast. This uses numpy.asanyarray to convert the input. Whether this is the desired result or not depends on the array subclass.
