Biased and Unbiased Estimation of the Circular Mean Resultant
... In many applications, the MRL is used to test if there is a strong preferred direction in measured data. It is argued that this is the case if the sample MRL exceeds a certain threshold which is chosen arbitrarily. However, due to the MRL’s variance and bias, such a strategy can be misleading, espec ...
