The definition of unbiased is a neutral person or persons. An example of unbiased is a jury with no prior knowledge of the case upon which they are deciding. or unÂ·biâ²assed. without bias or prejudice; objective; impartial.
Following the previous description of unbiasedness, a forecast will be unbiased for Î³ = Ï/4, while all forecast errors will have an angle Î³ between 0 and Ï/2. Instead of using Î³ that is expressed radians, we can define the Bias Coefficient : The bias coefficient is a unit-free metric. A forecast that is always over the observed values will have a bias coefficient equal to -1, always over-forecasting, while the bias coefficient will be equal to 1 for the opposite case. Let us visualise the bias coefficient in the following figure.
